How Much Down Payment You Really Need in Greater Boston (2026)

July 25, 2026 By Krista Recker

The short answer surprises most buyers: you do not need 20 percent down to buy a home in Greater Boston. Depending on the loan you use, you can buy with as little as 3 to 3.5 percent down, and some buyers who qualify put nothing down at all. Twenty percent is a target that helps you avoid mortgage insurance and strengthen an offer, but it is not a requirement, and waiting until you have it is often the most expensive decision a buyer makes.

Here is what actually drives the number: the loan program you choose, your credit, and how competitive you want your offer to be in the town you are targeting. This post breaks down the real minimums, what changes when you put down more, and how to think about the trade-off in a market like ours.

Who this applies to

If you are buying a primary home in Greater Boston or on the South Shore, this is for you. That includes first-time buyers, people moving up or down, and buyers relocating into the area. Investment properties and second homes follow different, higher down payment rules, so if that is your situation, the minimums below do not apply to you. Everything here assumes a home you plan to live in.

The real minimums by loan type

Your down payment floor is set by the loan program, not by your agent or the seller. These are the common paths for owner-occupant buyers.

A few things worth understanding underneath that table. Conventional loans let qualified buyers, often first-timers, start at 3 percent, but many buyers land at 5 percent. FHA is the widely used low-credit-friendly option at 3.5 percent, with the trade-off that its mortgage insurance often stays for the life of the loan unless you refinance. VA loans are one of the strongest tools available and are underused, so if you or your spouse served, ask about eligibility before assuming you cannot buy.

Massachusetts also runs programs built for buyers who have income but not a big pile of savings. ONE Mortgage, offered through the Massachusetts Housing Partnership, is a fixed-rate loan with 3 percent down and no private mortgage insurance, which lowers the monthly payment meaningfully. MassHousing offers loans with low down payments and down payment assistance that can help cover part of what you bring to the table. These programs have income limits and other requirements, and the exact dollars change over time, so treat them as options to qualify for rather than guarantees.

What changes when you put more down

More money down is not just about clearing a minimum. It changes three things at once.

Your monthly payment. A larger down payment means a smaller loan, which lowers what you pay every month before you even factor in insurance.

Whether you pay private mortgage insurance. On a conventional loan, putting less than 20 percent down means you pay private mortgage insurance until you reach roughly 20 percent equity, at which point you can request removal, and it automatically cancels near 22 percent equity by law. This is a real monthly cost, but it is also the price of getting into a home years earlier, and it is not permanent.

How your offer looks to a seller. In a competitive town, a stronger down payment can signal a more secure buyer, especially when paired with a solid pre-approval. It does not need to be 20 percent to be credible, but it is part of the picture a listing agent weighs.

The cost of waiting for 20 percent

Here is the trade most buyers do not run the numbers on. Saving from a low down payment up to a full 20 percent in Greater Boston can take years, and during those years two things usually work against you. Home prices in strong South Shore and Greater Boston towns have generally kept climbing, so the 20 percent target itself keeps moving higher. And you are paying rent the whole time instead of building equity.

Buying earlier with mortgage insurance, then removing that insurance later as your equity grows, often costs less over time than waiting to avoid it entirely. That will not be true for everyone, and it depends on your rate, your town, and how disciplined a saver you are. But the assumption that you must have 20 percent is the single most common reason capable buyers sit on the sidelines longer than they needed to.

Do not forget the money beyond the down payment

Your down payment is not the only cash you need at the table. In Massachusetts, plan for closing costs, which for buyers typically run about 2 to 5 percent of the price, plus your deposits along the way. When you go under contract here, you usually put down a small good-faith deposit with the offer, then a larger deposit at the purchase and sale agreement. That total deposit amount is negotiated rather than fixed by any rule, though it commonly lands around 3 to 5 percent of the price, and it is generally credited toward the funds you owe at closing. So it is not extra money, but you do need it liquid and ready earlier than closing day. A lender and a good agent will map this out for you so nothing is a surprise.

How to position yourself

Start with a real pre-approval, not a quick online estimate, so you know which programs you qualify for and what your true minimum is. Ask your lender directly about conventional 3 percent options, FHA, VA if you are eligible, and the Massachusetts programs like ONE Mortgage and MassHousing. Then decide how much to put down based on your monthly comfort level and how competitive your target town is, not on a 20 percent rule you inherited from someone else. The right number is the one that gets you into the right home on payments you can live with.

The Bottom Line

You need far less than most people think to buy in Greater Boston. The minimums start at 0 to 3.5 percent depending on the program, and Massachusetts has loans designed specifically for buyers who have income but limited savings. Twenty percent is a useful goal, not a gate. The more important question is not how do I reach 20 percent, it is which program fits me, what payment can I carry, and what does it actually cost me to wait. Answer those and you will make a far better decision than the buyer who is still saving for a number that keeps moving.

Frequently asked questions

Can I really buy a home in Greater Boston with 3 percent down? Yes. Conventional loans allow qualified buyers to put down as little as 3 percent, FHA allows 3.5 percent, and Massachusetts programs like ONE Mortgage offer 3 percent down with no private mortgage insurance. The right option depends on your credit, income, and the town you are buying in.

Do I have to pay private mortgage insurance forever? No. On a conventional loan, private mortgage insurance can be removed once you reach about 20 percent equity, and it cancels automatically by law near 22 percent equity. FHA mortgage insurance is different and often stays for the life of the loan unless you refinance, which is one reason to compare loan types carefully.

Is it smarter to wait until I have 20 percent down? Usually not, though it depends on your situation. Waiting means more years of rising prices and paying rent instead of building equity, while the 20 percent target keeps climbing. For many buyers, buying earlier with mortgage insurance and removing it later costs less overall than waiting.

How much total cash do I need beyond the down payment? Plan for closing costs, which for buyers in Massachusetts typically run about 2 to 5 percent of the purchase price, plus your deposits. Your deposit amount is negotiated rather than set by rule, often landing around 3 to 5 percent, and it is credited toward the funds you owe at closing, but you need it liquid before then.

What is the best low down payment loan in Massachusetts? There is no single best one. VA is unmatched if you are eligible. ONE Mortgage and MassHousing are strong for income-eligible buyers because they keep monthly costs down. Conventional and FHA are the broad options for everyone else. A lender should walk you through which one actually fits your numbers.
