The Boston loan limit is $962,550, not $1.25 million. Here is why that matters.
If you are buying near Boston and pricing out a conforming loan, one number online is wrong on a lot of sites. The 2026 high-cost limit for the Boston-metro counties is $962,550, not the $1,249,125 ceiling many pages quote. In an expensive market, that gap decides whether your loan is conforming or jumbo.
The number most sites get wrong
The FHFA sets a baseline conforming limit of $832,750 for 2026 and a high-cost ceiling of $1,249,125. High-cost counties fall somewhere between the two, based on local home prices. For the Boston-metro counties, Suffolk, Middlesex, Norfolk, Essex, and Plymouth, the 2026 figure is $962,550. Both conforming and FHA limits land on that same number in these counties, which is unusual. Only Dukes and Nantucket, the island counties, reach the full $1,249,125 ceiling. Barnstable and the western counties use the $832,750 baseline.

Why the gap matters
The Boston median is high, so plenty of ordinary homes sit between $962,550 and $1,249,125. If a website tells you the Boston limit is $1.25 million, you might assume a $1.1 million purchase is a conforming loan. In Suffolk or Middlesex, it is not. It is a jumbo, with stricter underwriting, a larger down payment, and different pricing. Knowing the real $962,550 line up front lets you plan the down payment and the loan type correctly, rather than finding out late in the deal.
What to do when you cross the line
Crossing the high-cost limit is common in Greater Boston, and it is not a problem, just a different loan. Mike runs both agency and jumbo, so a price above $962,550 in Suffolk or below it in Worcester gets the right structure either way. If you are close to the line, a slightly larger down payment can sometimes keep you conforming, which is worth modeling before you write the offer. The closing-cost page covers the limits by county, and the assistance page shows how MassHousing and the ONE Mortgage fit.
Massachusetts loan limit FAQ
What is the Boston conforming loan limit for 2026?
$962,550 in Suffolk, Middlesex, Norfolk, Essex, and Plymouth counties, for both conforming and FHA loans, which match in the Boston metro. It is not $1,249,125, the ceiling that many websites quote for the whole area. Only Dukes and Nantucket reach that ceiling. The rest of Massachusetts uses the $832,750 baseline.
Which Massachusetts counties have the highest loan limit?
Dukes and Nantucket, the island counties, at $1,249,125 for 2026. The Boston-metro counties are next at $962,550. Barnstable, on Cape Cod, and the western and central counties use the $832,750 baseline. So the limit depends heavily on which county you buy in, which is easy to get wrong in an expensive state.
Is a $1 million Boston home a jumbo loan?
If your loan amount is above $962,550 in a Boston-metro county, yes, it is a jumbo, even though some sites suggest the limit is higher. A larger down payment can sometimes bring the loan under the conforming line, which is worth checking. Jumbo underwriting is stricter, so knowing the real limit early helps you plan the down payment.
