New Condo Lending Rules Take Effect August 3: What Boston Buyers and Sellers Need to Know
If you are buying or selling a condo in Greater Boston this year, a change to how condos qualify for conventional financing could quietly make or break your deal. It has nothing to do with your credit score or your down payment. It has to do with the building.
Starting August 3, 2026, Fannie Mae and Freddie Mac are retiring the "Limited Review" process that used to let many condo loans move through underwriting with light paperwork. After that date, the vast majority of condo projects with more than 10 units will be pushed into a Full Review, where the lender digs into the association's budget, reserves, insurance, and any pending litigation before approving the loan.
Here is what that actually means for you, whether you are on the buying side or the selling side.
Why this is happening
The short version: aging buildings and underfunded reserves.
After the 2021 Surfside condo collapse in Florida, Fannie Mae and Freddie Mac began tightening the standards a building has to meet for its units to qualify for conventional mortgages. The two agencies back most conventional loans in the country, so their rules effectively set the bar for what lenders will and will not finance. The August 3 change is the latest step, formalized in Fannie Mae's Lender Letter LL-2026-03 and a matching Freddie Mac bulletin issued in March.
The goal is to make sure buildings have enough money set aside for major repairs before a buyer takes on a 30-year loan there. Reasonable in theory. The practical effect is more scrutiny on the building itself.
A second change is coming in 2027: higher reserve requirements
August 3 is the near-term deadline, but it is not the only one. A second change lands January 4, 2027, and it goes straight to a building's bank account.
For loan applications dated on or after that date, a condo project will generally need to set aside at least 15 percent of its annual budget for replacement reserves, up from the current 10 percent. Reserve studies also carry more weight, with lenders increasingly expecting associations to fund at the highest recommended level rather than the bare minimum.
In plain terms: buildings that have been running lean on reserves may need to raise their monthly dues or pass a special assessment to stay eligible for conventional financing. That is something both buyers and sellers should have on their radar now, well before the deadline arrives.
For buyers, it means a building that looks healthy today could be facing a dues increase to meet the new threshold. Ask where the association stands on reserves and whether any budget changes are planned.
For sellers, it means boards that have kept dues artificially low may have a reckoning coming. If your association is underfunded, it is better to understand that and get ahead of it than to have a buyer's lender flag it for you.
If you are buying
A strong borrower can now be denied financing because of the building, not because of anything in your file.
Under Full Review, the underwriter looks at the association's reserve funding, its insurance coverage, delinquency rates among owners, and whether there is active litigation or deferred maintenance. If the building falls short, your conventional loan can be delayed or denied even though you personally qualify.
What to do:
- Ask about the building early. Before you fall in love with a unit, your agent and lender should confirm the project's review status and flag any red flags in the association's finances.
- Build in time. Full Review takes longer and requires more documents from the association. Give your timeline some cushion so a slow document request does not blow up your closing date.
- Know your backup options. If a building does not qualify for conventional financing, other loan types or a larger down payment may still work. Better to know that on day one than the week before closing.
If you are selling
This is the part sellers tend to underestimate. Your buyer's financing now depends on your building's paperwork being in order.
If your association has thin reserves, an expired reserve study, lapsed insurance documentation, or unresolved litigation, you could see conventional buyers walk away or loans fall through late in the process. In a building with shaky finances, that can shrink your buyer pool to cash offers, which usually come in lower.
What to do:
- Get ahead of the documents. Reach out to your property manager or board now and confirm the association's budget, reserve study, and insurance certificates are current and easy to produce.
- Understand your building's standing. If your project has known issues, price and position accordingly, and be ready to be transparent with buyers and their lenders.
- Smaller buildings, take note. There is some relief built into these changes for very small projects. The waiver that lets a building skip Full Review now covers developments with 10 or fewer units, up from the old limit of four, with some conditions for projects in the 5 to 10 unit range. If you own in a small building, ask your agent how this applies to you.
The bottom line
These rules do not change whether condos are a good buy. Greater Boston condos remain one of the most accessible ways into homeownership in this market. What changes is that the building's financial health is now part of the deal in a way it was not before, for both sides of the table.
The buyers and sellers who come out ahead are the ones who treat the building as part of the due diligence from day one, not a surprise at the closing table.
If you have a Boston condo you are thinking about selling, or you are shopping and want to avoid getting blindsided by a building that will not qualify, we are happy to help you size it up before you are too far down the road. Reach out anytime.
