New Condo Financing Rules Every Boston Buyer Should Know

Will New Fannie Mae and Freddie Mac Condo Rules Affect Your Boston Purchase?

Starting August 3, 2026, Fannie Mae and Freddie Mac are retiring the streamlined "Limited Review" process for condo loans — meaning every conventional condo purchase, regardless of down payment size or credit score, now requires a full review of the building's finances.  HOAs also face a higher reserve requirement (15% of the annual budget, up from 10%, phased in through January 2027) and a new cap on master insurance policy deductibles.  In Boston, Brookline, and Newton, where much of the condo stock predates 1960, buildings with thin reserves or outdated financials risk losing "warrantable" status — which can knock a well-qualified buyer out of conventional financing entirely.

If you're shopping for a condo in Greater Boston right now, you've probably noticed the market has shifted in your favor.  Inventory is up 7% to 15% year-over-year, price reductions are common, and roughly 44% of sales now involve some kind of seller concession.  It feels like a good time to buy.

But there's a financing shift happening at the same time that has nothing to do with price, and everything to do with whether you can actually get a conventional loan on the building you want.

I've been walking buyers through this for the past few months, and it catches almost everyone off guard.  You can have a 780 credit score and 25% down, and still lose your financing — not because of anything about you, but because of the building.

What Changes on August 3, 2026

Fannie Mae and Freddie Mac review condo associations before they'll back a mortgage in that building.  For years, well-established buildings could qualify for a "Limited Review" — a fast, light-touch check that let strong buyers close quickly.

That fast-track option disappears on August 3, 2026.  After that date, every conventional condo loan application goes through a Full Review, no exceptions.  Your lender has to dig into the association's budget, reserve funding, insurance, and meeting minutes before your loan can close.

A few other changes are stacking on top of that:

• Reserve funding is going up.  HOAs must budget at least 15% of their annual income toward reserves, up from 10% — unless the building has a reserve study completed within the last three years that supports the highest recommended funding level.  This takes full effect for budgets in place by January 4, 2027, but lenders are already underwriting toward it now.
• Insurance deductibles are capped.  If a building's master property insurance policy has a per-unit deductible over $50,000 (effective July 1, 2026), the building is automatically classified as non-warrantable — no exceptions, no appeals.
• One thing did loosen up.  The old rule that flagged a building as non-warrantable if more than 50% of units were investor-owned was eliminated in March 2026.  That's a rare piece of good news in this update.

The net effect: a building that sailed through financing eighteen months ago might not qualify today, even with nothing about the building actually changing.  What changed is how closely lenders are required to look.

Why Boston's Older Condo Stock Is Especially Exposed

This matters more here than in most markets.  Greater Boston has an enormous inventory of pre-war and mid-century conversions — triple-deckers turned condos in Dorchester and Jamaica Plain, brownstone conversions in Back Bay and Beacon Hill, and older multi-unit buildings throughout Brookline, where more than half the housing stock was built before 1939.

Older buildings tend to have exactly the profile that trips up the new rules: aging roofs, masonry, and mechanical systems; reserve studies that are five or ten years old, if they exist at all; and monthly fees that were set years ago and haven't kept pace with what capital repairs actually cost.

I'm also watching this collide with the soft luxury condo market right now.  Historic Back Bay and Beacon Hill units at $2 million and up have been sitting for 200-plus days in some cases and selling well under asking — which looks like an opportunity.  It can be.  But a discounted price on a building with an underfunded reserve account is not the deal it appears to be if you can't get a conventional loan to close on it, or if a special assessment lands on your desk six months after you move in.

If a building does lose warrantable status, your financing options narrow fast.  You're generally looking at a portfolio or DSCR loan instead of a conventional mortgage — typically 20% to 30% down, with rates running one to two points higher, or a pricing premium of half a point to a point and a half tacked onto an otherwise-conventional loan.  On a $1.2 million Brookline condo, that's not a rounding error.

How to Protect Yourself Before You Make an Offer

The mistake I see buyers make is waiting until they're under agreement to find out whether a building is warrantable.  By then, you're on the clock, and if the building fails review, you're either walking away from your deposit timeline or scrambling for a portfolio lender at a worse rate.  Here's how to get ahead of it instead:

1. Ask for the reserve study and current budget before you write an offer.  You want to know what percentage of the annual budget is going to reserves and whether a reserve study has been done in the last three years.
2. Ask about the master insurance policy deductible.  If it's above $50,000 per unit, treat that as a real red flag, not a technicality.
3. Loop your lender in early — not just for prequalification, but on the specific building.  A good lender can flag likely warrantability issues before you're emotionally attached to a unit.
4. Don't assume a building that qualified last year still qualifies today.  The Full Review requirement means the bar moved, even for buildings with a clean track record.

This is exactly the kind of due diligence I walk buyers through before they ever write an offer — it's a lot easier to solve for financing risk up front than to renegotiate it after you're under contract. And if you're reviewing condo documents as part of your purchase, it's worth pairing this with a full understanding of what Massachusetts requires in a condo document review before you sign the P&S.

It's also worth revisiting how much cash you actually need to buy in Boston if there's any chance the building you're eyeing could fall into non-warrantable territory — a 20-30% down payment requirement changes the math significantly from a standard 5-10% down conventional purchase.

Frequently Asked Questions

What makes a condo "non-warrantable"?

A condo becomes non-warrantable when it fails to meet Fannie Mae or Freddie Mac's financial or structural standards — most commonly due to underfunded reserves, an outdated reserve study, ongoing litigation, too much commercial space in the building, or a master insurance policy with a per-unit deductible above $50,000.  Once a building is non-warrantable, conventional financing isn't available for any unit in it.

I'm already under agreement on a condo — does this affect me?

It depends on when your loan application is dated.  The Full Review requirement applies to conventional loan applications dated on or after August 3, 2026.  If you're already in underwriting before that date, ask your lender directly whether your specific file falls under the old or new review standard.

How do I check a building's reserve funding before I make an offer?

Ask the listing agent or seller for the association's current budget, most recent reserve study, and the last 12 to 24 months of meeting minutes.  If the association can't produce a reserve study from the last three years, that's worth raising with your lender before you get too far into the process.

Will my HOA fees go up because of this?

Possibly.  Associations that need to raise their reserve allocation from 10% to 15% of their budget will likely need to raise monthly fees, issue a special assessment, or both.  It's worth asking directly whether the board has discussed a fee increase in response to the new requirements.

Does this apply to new construction condos too?

New construction and newly converted buildings go through a separate "new project" review process, which already tends to be more rigorous than the old Limited Review.  The August 2026 change primarily affects established buildings that previously qualified for the streamlined review.

If you're weighing a condo purchase anywhere in Boston, Brookline, Newton, Needham, Dedham, or Milton and want a second set of eyes on a building's financials before you write an offer, I'm happy to walk through it with you.  Reach out anytime.
