The 135% AMI Rule Change: How Somerville's 'Missing Middle'

Key Takeaways

You may qualify even on a strong salary: Households earning up to 135% of area median income (AMI) — the eastern Massachusetts regional figure, not a Somerville-specific one — can now tap MassHousing's first-time buyer help. Have a lender confirm your exact current limit before you budget.
The offer: Up to $25,000 toward your down payment, closing costs, prepaid mortgage insurance, or an interest-rate buydown (paying upfront to lower your monthly rate). It's structured as a deferred second loan — repaid later, not monthly.
The catch on timing: The special 0% interest version proved so popular it closed early. If you're starting your search now, that round isn't available to you. The standard program remains open.
The bottom line: Talk to a MassHousing-approved lender this week, and ask whether Somerville's own local aid can stack on top.
# What Should Somerville First-Time Buyers Know About MassHousing's $25,000 Help?
Watching the MassHousing deadline? Here's the plain version: the most generous 0% interest window closed early, but the broader down payment assistance program still matters for Somerville buyers.
This isn't just for very low incomes anymore. MassHousing raised the income ceiling to 135% of area median income (AMI) — the typical income level for a region. Before you build a budget around it, have a lender confirm your exact current limit.

That's the major change. It means many Somerville teachers, nurses, city workers, and dual-income households who earned too much under older limits may now qualify.
The core offer: up to $25,000 for your down payment, closing costs, prepaid mortgage insurance, or an interest-rate buydown.

Do You Qualify as a Somerville Buyer?

Three things matter most.
First-time buyer status: Rules on who counts as a first-time buyer vary. Confirm the current definition with your lender.
Income: Your total qualifying income must sit at or below the 135% AMI eastern Massachusetts regional cap.
Loan type: You need a MassHousing mortgage through a participating lender.
You don't apply directly to the state. You start with a MassHousing-approved lender, who checks your income, your loan fit, and whether the assistance can attach to your mortgage.
One honest note: the standard program tops out at $25,000. Against a local market where homes often exceed a million dollars, that covers only a small share of the purchase price — useful for closing costs or part of a down payment, but not a fix for the whole affordability gap.

What Are the Biggest Concerns?

"Does a high income cap help people who don't need help?"
In many towns, that's a fair question. In Somerville, prices run high enough that even strong-income households struggle to save cash while covering local rents. That's the "missing middle" problem.
"Is the cap a Somerville-specific number?"
No. It's the eastern Massachusetts regional cap. MassHousing sets income limits by region, not by individual city.
"Did I miss the 0% deadline?"
If you're starting your search now, yes — that specific 0% expansion round has closed, and you shouldn't count on it. Be honest with yourself about that. What remains is the standard $25,000 assistance program, so ask a MassHousing lender to confirm current deadlines and terms rather than relying on any single date you've seen elsewhere.

What Should You Do This Week?

Somerville may offer one more advantage: its own local down payment assistance program. Ask your lender whether it can stack with MassHousing's. If it can, that may lower the cash you need at closing.
Also plan for buyer-agent costs. Under a recent change to state buyer-agency rules, you may need to sign a written buyer-agency agreement before touring homes, and buyer-agent fees can be negotiable — confirm the current requirements with your agent.
Your next steps:
Confirm your first-time buyer status with a lender.
Ask a lender how the 135% AMI cap applies to your income.
Call a MassHousing-approved lender.
Ask about Somerville local assistance.

Common Questions

What income do Somerville buyers need to qualify for MassHousing’s $25,000 assistance?

Somerville buyers may qualify if household income on the mortgage is at or below $205,335, the eastern Massachusetts 135% AMI cap used for Somerville. The buyer also must be a first-time buyer, meaning no principal residence owned in the past three years, and use a MassHousing-approved lender.

Can Somerville down payment assistance be combined with MassHousing’s program?

Somerville buyers should ask their lender whether Somerville down payment assistance can stack with MassHousing’s $25,000 loan. The article says Somerville runs its own independent aid and it may combine with the state program, but buyers must confirm the rules directly with a MassHousing-approved lender.

Is the 0% MassHousing down payment assistance still available after the July deadline?

The special 0% interest version is no longer available, because buyers had to lock a MassHousing mortgage by July 2, 2026. The standard $25,000 program stays open, but August buyers should confirm current terms, including any Somerville 135% AMI access, with a participating lender.
