Condo Mortgage Rules Just Changed for 2026, and There's a New Underwriter at Your Closing Table

If you're buying or selling a condo right now, there's someone new sitting in on the deal. You've never met them. They've never seen the unit. But as of this month, they have more say over whether your sale closes than almost anyone else in the room.
Fannie Mae and Freddie Mac just finished rolling out the biggest change to condo lending in years, and the last piece of it landed August 3. I want to walk you through what actually changed, because it's not a headline, it's the kind of thing that quietly kills a deal in week five if nobody saw it coming.
What the new condo mortgage rules for 2026 actually change
For a long time, most condo loans got what's called a Limited Review. Quick, light, minimal digging into the building's finances. As of August 3, that option is gone for the vast majority of loans. Almost every condo loan now goes through Full Review, which means the lender is actually looking at the association's budget, its reserves, its insurance, its litigation history, how many owners are behind on dues, and whether the building has any deferred maintenance.
And here's the part that matters most: if a building has critical repairs on the books that cost more than $10,000 per unit and hasn't set aside the money to cover them, that building can become ineligible for conventional financing. Not the buyer. The building.
There's also a new cap on insurance deductibles, and a bump in required reserve funding from 10% of the budget to 15%, phasing in over the next several months.
Why this matters more than it sounds like it does
None of this touches whether you personally qualify for a mortgage. It touches whether the building you're buying into qualifies. I've had buyers with excellent credit and a healthy down payment get to the finish line and hit a wall because the association's reserve study was five years old, or the roof repair everyone knew about never made it into the budget.
This is especially true in a lot of our vintage buildings. The six flat converted to condos in the 1980s. The self-managed building where the board hasn't raised assessments in a decade because nobody wants that conversation. Those buildings aren't bad buildings. But they're exactly the ones that can get caught by this.
What I'm telling buyers
Ask for the reserve study before you fall in love with the unit. Ask when it was last updated. Ask what percentage of the budget is going to reserves. If the listing agent doesn't know, that's information too.
What I'm telling sellers
If you're in a self-managed building or one that hasn't touched its reserve study in a while, get ahead of it now, not after you've accepted an offer. A board that can produce clean financials and a current reserve study is doing every seller in that building a favor. A board that can't is going to watch buyers walk, or watch deals collapse in underwriting instead of at the table where you can still fix it.
The bigger picture
This is going to sort buildings into two groups over the next year. Buildings that get their paperwork and their reserves in order, and buildings that quietly become harder to sell, not because of the unit, not because of the neighborhood, but because of a budget line item nobody wanted to deal with.
If you're touring condos this fall or thinking about listing one, this is worth a conversation before you're five weeks into a deal. Send me a mesage and I'll walk you through what to ask.
