Buying a Condo with a Mortgage is Getting More Complicated Across the U.S.: What You Need to Know

Planning to buy a condo with a mortgage? Major underwriting changes from Fannie Mae and Freddie Mac mean lenders are scrutinizing building finances and reserves more than ever. Here is what buyers and sellers need to know to avoid loan delays.

If you are planning to purchase a condominium using a mortgage, your lender is about to scrutinize your prospective building’s budget just as rigorously as they inspect your personal finances.

Updated condo underwriting guidelines from Fannie Mae and Freddie Mac take effect this August, introducing stricter requirements that could impact approval timelines, reserve budgets, and overall loan eligibility. Here is what buyers, sellers, and condo board members need to know to stay ahead of the changes.

What’s Changing in Condo Financing?

Fannie Mae and Freddie Mac, the government-sponsored enterprises that buy and guarantee the majority of U.S. residential mortgages, announced sweeping updates aimed at curbing financial and structural risk in multi-family buildings.

The main shifts taking center stage include:

The Elimination of “Limited Reviews”
Historically, roughly 40% of condo mortgage applications qualified for streamlined, “limited” building reviews. Under the new rules, most purchases will require a comprehensive full review of the association’s financial health, insurance policies, reserve accounts, and physical condition.

Higher Required Budget Reserves
A subsequent requirement taking effect in January requires condo associations seeking Fannie or Freddie financing to allocate at least 15% of their annual budget toward reserve funds for major repairs (up from 10%).

Increased Documentation
Lenders will require detailed board questionnaires, financial statements, and structural inspection records before greenlighting a loan.

Why Are Lending Rules Tightening?

These policy shifts follow nationwide reform efforts in the wake of the tragic 2021 condo building collapse in Surfside, Florida. Subsequent investigations highlighted how decades of deferred maintenance, structural defects, and insufficient reserve funds can compromise safety and lead to catastrophic financial burdens for unit owners.

By raising underwriting standards, secondary market buyers aim to ensure condo associations maintain adequate capital to address major structural repairs long before emergency special assessments become necessary.

Potential Challenges for Buyers and Sellers

While these regulations are intended to protect buyers from high-risk buildings, industry experts warn that the transition will create temporary friction in the market:

  1. Longer Approval Timelines: Completing full project reviews requires manual verification across multiple municipal and association documents. Buyers should anticipate longer underwriting periods during escrow.
  2. More Disqualifying Applications: Buildings that fail to meet strict reserve ratios or carry minor documentation nuances could be rendered ineligible for conventional financing, even if the building itself is physically sound. This does not mean a buyer cannot get financing at all. It just means they will not be able to use a conventional loan.
  3. Higher Costs for Alternative Loans: Buyers seeking mortgages in unapproved buildings may need to rely on portfolio lenders who hold loans on their own books. These alternative loans often require larger down payments or carry higher interest rates to offset risk.

The Silver Lining: Approved Status Makes For Faster Approvals

The good news? Once a condominium development successfully passes a full lender review, it is cataloged as approved in Fannie Mae and Freddie Mac’s systems. Future buyers in that building will generally not have to undergo a full review from scratch, no matter which bank they use, expediting subsequent transactions.
