The 2026 Boston First-Time Homebuyer Guide: Programs, Down Payments & What You Actually Need to Save

You probably don’t need 20% down to buy your first home in Boston. But your down payment isn’t the only number you need to save for.

For a Boston first-time homebuyer, saving for a home can feel like chasing a finish line that keeps moving. Home prices are high, mortgage rates remain elevated, and conventional wisdom still tells many renters they need 20% down before they should even think about buying.

The reality is more complicated, and in some ways more encouraging.

Several mortgage programs allow qualified first-time buyers to purchase with 3% to 3.5% down, while Massachusetts and the City of Boston offer programs that can provide substantial down payment and closing-cost assistance. Massachusetts’ ONE Mortgage requires as little as 3% down on many property types and eliminates private mortgage insurance, while MassHousing currently advertises down payment assistance of up to $30,000 for eligible buyers. Boston has additional programs for buyers purchasing within city limits.

But here’s the part that deserves more attention: the down payment is not the same thing as the amount you need to save.

There are closing costs, inspections, prepaid taxes and insurance, moving expenses, emergency reserves, and the inevitable first-month surprises that accompany homeownership. And in Greater Boston, where even a relatively modest condo can carry a substantial price tag, understanding those numbers before you start touring homes can completely change your strategy.

This guide breaks down what first-time buyers actually need in 2026, which programs may help, and how to build a realistic savings target without waiting unnecessarily for the mythical 20%.

Key Takeaways

• You do not automatically need 20% down to buy your first home.
• Some conventional programs begin around 3% down, while FHA commonly allows 3.5%; Massachusetts’ ONE Mortgage requires 3% for qualifying condos, single-family and two-family properties.
• Closing costs are separate from your down payment and can often equal roughly 2% to 5% of the purchase price.
• MassHousing currently offers eligible buyers down payment assistance of up to $30,000.
• Boston’s First-Time Homebuyer Program can provide eligible buyers purchasing in Boston with assistance of up to $50,000, depending on income and other qualifications.
• Your ideal savings target should include cash for closing plus money you keep after closing.
• Your first conversation with a lender should happen well before you believe you’re “ready to buy.”

What Counts as a First-Time Homebuyer?

Here’s the first surprise.

“First-time homebuyer” doesn’t always mean you’ve never owned a home before.

For several major Massachusetts programs, you may qualify as a first-time buyer if you haven’t owned a home during the previous three years.

Massachusetts’ ONE Mortgage uses that definition. The City of Boston’s First-Time Homebuyer Program does as well. That distinction matters.

Someone who owned a condo years ago, sold it, and has been renting ever since could potentially qualify for programs they assumed were permanently off the table.

Eligibility varies by program, however. Income, assets, property type, occupancy, location and homebuyer education requirements may all apply. So before deciding that you “don’t qualify for first-time buyer programs,” check.

You might be leaving thousands of dollars of assistance unexplored.

Do Boston First-Time Homebuyers Really Need 20% Down?

No. The 20% down payment is probably the most persistent myth surrounding homeownership.

Putting 20% down has real advantages. It reduces the amount you’re borrowing and can eliminate private mortgage insurance on many conventional loans. It can also lower the monthly payment and make an offer financially stronger.

But it is not a universal entrance fee for homeownership.

The Consumer Financial Protection Bureau notes that many mortgages require at least 3% down, while others commonly require 5% or more. Fannie Mae’s HomeReady mortgage advertises down payments as low as 3%, while FHA-insured mortgages can require as little as 3.5% in many circumstances.

Massachusetts buyers have another important option.

ONE Mortgage requires just 3% down for an eligible condo, single-family or two-family property and 5% for a three-family property. It also does not charge private mortgage insurance. That creates a radically different savings equation.

Consider a $600,000 home.

Twenty percent down would be:

$120,000.

Five percent would be:

$30,000.

Three percent would be:

$18,000.

Those are three very different doors into the same purchase price. The right question therefore isn’t:

“How do I save 20%?”

It’s:

“Which financing strategy makes sense for my income, savings, monthly budget and long-term plans?”

How Much Do You Actually Need to Save to Buy a Home in Boston?

This is where we need to separate two numbers buyers frequently combine:

Your down payment and Your cash-to-close strategy.

Your down payment is only one component.

The CFPB recommends considering your down payment alongside closing costs, moving expenses, renovations or initial repairs, and an emergency cushion. It estimates closing costs alone commonly run around 2% to 5% of the purchase price, excluding the down payment.

So if you’re looking at a $600,000 condo with 5% down, the calculation shouldn’t simply be:

$600,000 × 5% = $30,000. Done.

Your actual financial picture might include the $30,000 down payment, closing expenses, inspection and due-diligence costs, prepaid insurance and taxes, moving expenses, and cash you intentionally preserve after closing.

That last category is important.

Buying a home with $60,000 available and spending $59,800 to get through the front door may technically get you there.

It doesn’t necessarily leave you in a comfortable financial position once you own it.

What Do You Actually Need to Save? Three Boston Buyer Scenarios

Let’s put some numbers around this.

These are planning examples, not loan quotes. Actual closing costs and mortgage requirements vary considerably.

A $500,000 Purchase

At 3% down, the down payment is $15,000.

At 5%, it is $25,000.

At 10%, it becomes $50,000.

A rough 2% to 5% closing-cost planning range would add another $10,000 to $25,000 before considering any assistance, seller credits or lender credits.

So a buyer using 3% down shouldn’t think, “I need $15,000.”

A better early planning conversation might start around $25,000 to $40,000+ for down payment and closing costs, before considering reserves and assistance.

A $650,000 Purchase

Three percent equals $19,500.

Five percent equals $32,500.

Ten percent equals $65,000.

Estimated closing costs using the CFPB’s broad range could fall around $13,000 to $32,500.

A 5%-down buyer might therefore be looking at roughly $45,500 to $65,000 before reserves, absent assistance or credits.

A $750,000 Purchase

Three percent equals $22,500.

Five percent equals $37,500.

Ten percent equals $75,000.

A 2% to 5% planning range for closing costs would equal approximately $15,000 to $37,500.

That means someone purchasing at $750,000 with 5% down might initially model $52,500 to $75,000 for down payment plus closing costs, before accounting for assistance, credits or the savings they want to retain.

And suddenly the question “How much do I need to save?” becomes much more useful than “How much is the down payment?”

🌳 Red Tree Take

Don’t build your homebuying plan backward from 20%. Build it forward from the monthly payment you can comfortably afford.

A buyer with $60,000 saved may discover that using every dollar toward a larger down payment isn’t their strongest option. Keeping some money in reserve while using an eligible low-down-payment or assistance program could create a healthier financial position after closing. The lender, buyer’s agent and buyer should be solving that puzzle together.

Boston & Massachusetts First-Time Homebuyer Programs in 2026

This is one of the most important parts of this guide.

Massachusetts buyers have access to a surprisingly deep ecosystem of homeownership programs. The catch is that the programs have different income limits, asset limits, property requirements, locations and participating lenders.

Three programs deserve particular attention:

ONE Mortgage, available statewide through participating lenders.

MassHousing mortgage and down payment assistance programs, also available throughout Massachusetts.

And, for properties within Boston, Boston Home Center programs, including the City’s First-Time Homebuyer Program and ONE+Boston.

These programs aren’t interchangeable.

And you shouldn’t assume that the program with the largest advertised assistance amount automatically produces the best mortgage.

Interest rate, mortgage insurance, second-mortgage repayment terms, monthly payment, income limits and property eligibility all matter.

ONE Mortgage: One of Massachusetts’ Most Important First-Time Buyer Programs

Massachusetts describes ONE Mortgage as the state’s most affordable mortgage for low- and moderate-income first-time buyers.

It is a 30-year fixed-rate mortgage available through more than 40 participating lenders.

Its standout features are significant:

3% down for a condo, single-family or two-family home.

5% down for a three-family property.

No private mortgage insurance.

Potential additional payment assistance for qualifying borrowers.

ONE Mortgage also permits eligible buyers to use down payment assistance or gifted funds toward the required down payment.

There are eligibility requirements.

Borrowers generally must meet household-income limits, occupy the home as their primary residence, complete an approved homebuyer course and satisfy credit requirements.

As of September 2026, Mass.gov lists minimum credit scores of 640 for a single-family home or condo and 660 for a two- or three-family property. Household assets generally must remain below $75,000, excluding most retirement and college savings accounts.

For a Boston buyer who assumes their choices are simply “conventional or FHA,” ONE Mortgage deserves a seat at the table.

ONE+Boston: An Even More Targeted Option for Boston Residents

For eligible Boston residents purchasing within the city, ONE+Boston builds on ONE Mortgage.

The City subsidizes the mortgage to provide a discounted fixed interest rate below the already discounted ONE Mortgage rate and combines it with access to enhanced down payment and closing-cost assistance.

As of the current 2026 program information, ONE+Boston requires:

3% down for a condo, single-family or two-family property, with at least 1.5% coming from the buyer’s own savings.

For a three-family property, the required down payment is 5%, with at least 3% from the buyer’s own savings.

Current household income limits range from $120,000 for a one-person household to $171,400 for a four-person household, increasing further for larger households. The program also sets a $100,000 household asset limit, excluding most retirement and college savings accounts.

Buyers of two- and three-family properties also have additional landlord-education requirements.

For someone already living in Boston who wants to remain in the city, ONE+Boston can materially change the affordability calculation.

Review current ONE+Boston eligibility

MassHousing Down Payment Assistance: Up to $30,000

MassHousing currently offers eligible first-time buyers up to $30,000 in down payment assistance when paired with an eligible MassHousing mortgage.

Unlike Boston-specific programs, MassHousing assistance can be used to purchase in any Massachusetts city or town, subject to program and first-mortgage eligibility.

The assistance isn’t necessarily free money.

Current options include a 0% deferred second mortgage of up to $30,000, as well as amortizing second-mortgage options of up to $25,000 carrying 2% or 3% interest. With the deferred option, repayment generally becomes due when the home is sold or refinanced or the first mortgage is paid off.

That’s an important distinction.

Earlier in 2026, Massachusetts temporarily expanded a separate 0% deferred $25,000 assistance option. That promotion ended early because of strong demand, and buyers researching the program may still encounter older articles advertising it. Current MassHousing information should therefore be used rather than assuming an older 2026 offer remains available.

See current MassHousing down payment assistance options

Boston Home Center: Assistance Up to $50,000

If you’re purchasing inside the City of Boston, the Boston Home Center should be one of your first research stops.

Its current First-Time Homebuyer Program provides income-eligible buyers with down payment and eligible closing-cost assistance.

For households below 100% of Area Median Income, assistance can equal up to 3% of the purchase price plus eligible closing costs, capped at $50,000.

For households between 101% and 135% of AMI, assistance can equal up to 2% of the purchase price plus eligible closing costs, capped at $35,000.

Eligible buyers generally must be purchasing a one- to three-family home or condo in Boston as their primary residence, complete an approved Homebuying 101 class, use a participating mortgage lender, meet income requirements and have household assets below $100,000.

There’s also an important September 2026 update.

For Boston residents, assistance is structured as a grant. Effective September 15, 2026, assistance for qualifying non-Boston residents is structured as a 0% interest deferred loan, repayable upon transfer, refinance or sale.

That is precisely why buyers should verify program terms at the time they’re preparing to purchase. Assistance programs evolve.

What Closing Costs Should a Boston First-Time Homebuyer Expect?

This is the expense most likely to surprise buyers who have focused exclusively on their down payment.

The CFPB recommends using roughly 2% to 5% of the purchase price as an early estimate for closing costs, although actual costs depend on your property, mortgage, lender and location.

Massachusetts closing expenses can include appraisal and lender fees, attorney expenses, title work and title insurance, recording fees, prepaid homeowners insurance, tax escrows and other loan or property-specific charges. Condominiums can introduce additional items related to the association and master insurance.

Some of these costs happen before closing.

Your inspection, for example, generally happens shortly after your offer is accepted. Depending on the property, buyers may also investigate radon, lead paint, pests or other conditions.

Your lender will eventually issue a formal Loan Estimate, which provides far more accurate information about your specific loan’s projected costs. Massachusetts guidance notes that lenders issue these disclosures within three business days after receiving a mortgage application.

Don’t treat a 2% to 5% estimate as a bill.

Treat it as a planning range until your lender gives you the real numbers.

Your Down Payment Is Only One Bucket

A healthier way to think about your savings is to divide it into several mental buckets.

There’s money for the purchase, including your down payment and closing expenses.

There’s money for the move, which might include movers, furniture, utility setup or immediate improvements.

And then there’s money for life after closing.

The CFPB recommends preserving an emergency cushion and notes that a common rule of thumb is approximately three to six months of expenses.

That doesn’t mean every buyer must have six months of expenses sitting untouched before buying.

It does mean that “the lender says I can close with this amount” and “I feel financially comfortable owning this home” are not always the same calculation.

Homeownership has a peculiar habit of introducing expenses about eleven minutes after you receive the keys.

A dishwasher stops cooperating. The water heater develops a personality. The condo association announces an assessment. The house needs something nobody noticed during the showing.

Cash reserves turn those events into annoyances rather than emergencies.

Credit, Income and Debt: What Lenders Actually Look At

Your savings account isn’t the only thing determining your buying power.

Mortgage lenders evaluate your income, existing debt, credit profile, assets, employment and the characteristics of the property you’re purchasing.

This is why two people earning the same salary can qualify for dramatically different mortgages.

Someone carrying a substantial car payment, student loan obligations and revolving credit-card debt has less monthly room available for housing than someone earning the same income with minimal recurring debt.

Credit matters as well, but buyers shouldn’t automatically assume that imperfect credit means they need to wait years.

For example, ONE Mortgage currently lists a minimum score of 640 for qualifying single-family homes and condos and 660 for two- and three-family properties. FHA loans are specifically designed with more flexible credit qualification than many conventional products, although individual lender standards can vary.

The useful move isn’t guessing whether your credit is “good enough.”

It’s speaking with a qualified lender early enough to identify what, if anything, needs improvement.

Can You Use Gift Money for a Down Payment?

Potentially, yes.

This is another area where buyers sometimes wait unnecessarily because they believe every dollar must come from their personal checking account.

Mortgage programs can allow eligible gift funds from family members or other permitted donors, subject to documentation and program rules.

ONE Mortgage explicitly states that gifted money from a family member may be used as part of the required down payment.

Nationally, family assistance isn’t unusual. NAR’s most recent buyer profile reported that 22% of first-time buyers used gifts or loans from relatives or friends as a source of down-payment funds. Personal savings remained the most common source.

But don’t move a large sum into your account the week before applying and assume nobody will ask about it.

Mortgage underwriting involves documenting assets and the source of funds. If family will be helping, tell your lender early so they can explain how the transfer and gift documentation should be handled.

Condo, Single-Family or Multifamily? Your Property Choice Changes the Math

Boston first-time buyers shouldn’t think only about price.

Property type matters.

For many buyers within Boston proper, a condominium may provide the most accessible route to ownership. But condo fees need to be incorporated into the monthly affordability calculation, and buyers should review the association’s budget, reserves, master insurance, governing documents and potential assessments.

A single-family home gives the owner greater autonomy but also transfers responsibility for essentially every repair directly to the homeowner.

Then there’s the distinctly Boston-area strategy of purchasing a two- or three-family property and occupying one unit.

For qualified buyers, rental income from other units may potentially factor into mortgage qualification depending on lender and loan-program rules. But becoming an owner-occupant also means becoming a landlord, complete with maintenance, tenant responsibilities and Massachusetts housing law.

ONE Mortgage illustrates how property type can affect financing directly: qualifying condos, single-family and two-family purchases require 3% down, while a three-family purchase requires 5%.

The cheapest property isn’t necessarily the cheapest property to own.

And the most expensive purchase price doesn’t necessarily create the highest net monthly housing cost.

You have to model the whole property.

Boston’s 2026 Market: Why Preparation Matters

Affordability remains the elephant squeezed into Boston’s very small living room.

Massachusetts’ August 2026 median sale price reached $695,000 for single-family homes and $565,000 for condominiums, while new listings increased 17% from a year earlier.

Greater Boston is more expensive still. Current regional reports place typical single-family pricing around the $1 million mark, while condos remain substantially below that but still expensive relative to national prices.

Mortgage rates add another layer.

Freddie Mac’s latest weekly survey, dated September 17, 2026, put the average 30-year fixed mortgage at 6.95%. That’s a national benchmark rather than the rate an individual Boston buyer should expect, but it demonstrates why monthly-payment planning matters so much in today’s market.

The encouraging development is inventory.

Massachusetts saw new single-family and condo listings rise 17% year over year in August. More choice doesn’t suddenly make Boston inexpensive, but it can give prepared buyers more opportunities to compare properties rather than treating every listing as a five-alarm emergency.

🌳 Red Tree Take

In 2026, buying power matters more than headline price.

A $650,000 property with a particular condo fee, tax bill and financing structure can produce a very different monthly payment from another $650,000 property.

That’s why we would rather have a first-time buyer understand their comfortable monthly number before falling in love with a listing.

Don’t Empty Your Savings Account Just to Reach 20%

Imagine two buyers.

Buyer A puts 20% down and finishes closing with almost no liquid savings.

Buyer B puts less down, retains a healthy emergency fund, and comfortably handles their monthly payment.

Which buyer is financially safer?

There isn’t enough information to answer. That’s the point.

Twenty percent down is not automatically the “responsible” option simply because the percentage is larger. A bigger down payment reduces the mortgage balance and generally lowers monthly borrowing costs. A smaller down payment preserves liquidity but can increase monthly costs and may introduce mortgage insurance.

The correct balance depends on the buyer. For first-time buyers in particular, cash after closing deserves its own line in the budget. Your goal isn’t simply to become a homeowner.

It’s to become a homeowner who can comfortably afford to remain one.

When Should You Get Pre-Approved?

Earlier than most buyers think.

You do not need to wait until you’ve saved your final dollar before speaking with a lender.

In fact, doing so can work against you.

A good early lender conversation can help establish whether you’re already financially positioned to buy, whether you qualify for assistance, how much different down payments change your monthly cost, and whether specific changes to debt or credit could improve your options.

For buyers interested in ONE Mortgage, ONE+Boston, MassHousing or Boston Home Center assistance, starting early is particularly useful because these programs have qualification, education and participating-lender requirements.

Boston Home Center applicants, for example, must complete an approved Homebuying 101 course and obtain pre-approval from a participating lender.

Pre-approval also gives your real estate agent something much more useful than a theoretical budget.

It gives everyone a real search range.

The Boston First-Time Homebuyer Roadmap

The process doesn’t need to begin on Zillow at midnight.

Start with education and finances. Understand your income, monthly obligations, available savings and comfortable housing payment.

Then speak with a lender, preferably one familiar with Massachusetts first-time buyer programs. Compare financing structures rather than asking only, “What’s your rate?”

Investigate assistance programs early. If a program requires homebuyer education, take the class before you’re under the pressure of an accepted offer.

Once your financing is clear, establish your search with a buyer’s agent and begin comparing not only homes, but neighborhoods, commuting patterns, condo costs, property taxes and long-term ownership expenses.

When the right property appears, you’ll be evaluating it from a position of preparation rather than trying to reverse-engineer your finances in 48 hours.

And that is where first-time buyers become much more competitive.

How Much Should You Save?

If you remember only one equation from this guide, make it this:

Savings Goal = Down Payment + Closing Costs + Moving/Initial Costs + Post-Closing Reserve − Confirmed Assistance

Not: Home Price × 20%

For a Boston first-time homebuyer, those two equations can lead to completely different timelines. Someone who believes they need $120,000 to purchase a $600,000 home might postpone buying for years.

Once they speak with a lender, they may discover that a lower-down-payment mortgage, assistance program, gifted funds or another financing structure creates a viable path much sooner.

Or they may discover that waiting and saving more genuinely is the better move.

Either outcome is useful.

The important part is making that decision from actual numbers rather than a rule of thumb inherited from another housing market and another era.
