Your mortgage now depends on your neighbours

It's one page. A letter from the condo association with a five-figure number on it and a due date ninety days out. You read it twice. Then you go and look up what units in your building have sold for lately.

I've had that conversation three times this year. It ends the same way every time. The owner isn't really asking about the roof. They're asking whether anyone will be able to buy their unit.

The answer to that question changed on August 3.

On March 18, Fannie Mae published a lender letter, LL-2026-03. Freddie Mac matched it the same day. The letter retires something called Limited Review.

Limited Review was the fast lane. If a buyer put enough money down and planned to live in the unit, the lender could skip the association's finances. No budget. No reserve study. No delinquency report. The loan was a judgment about the borrower.

That lane closed for every loan application dated on or after August 3. Established projects with more than ten units go through Full Review instead. The lender reads the association's operating budget, its reserve balances, its master insurance, its litigation, and how many owners are behind on their dues.

In other words, your buyer's mortgage now depends on your board's bookkeeping.

A mortgage used to be an opinion about a person. For a condo, it's now an opinion about a building.

There's a second date in the letter. From January 4, 2027, an association's budget has to put at least 15% of its annual assessment income into replacement reserves. The old floor was 10%.

Fannie also took away the workaround. Boards used to fund reserves on a baseline plan, where the balance drifts down toward zero and never quite touches it. Lenders can't accept that any more. If a lender leans on a reserve study instead of the budget line, the study's highest recommended funding level is the one that counts.

Fannie set out its reasoning in the letter. Projects with thin reserves turn out to be the same projects that need urgent repairs. Owners then get an assessment they never budgeted for. Some of them stop paying the mortgage.

So the rule exists because of the letter in your mailbox. It also makes that letter arrive sooner, and bigger.

That's the part I keep turning over. The board doesn't pay for this. Whoever needs to sell pays for it.

This connects directly to the part of a condo purchase most owners never see.

Fannie Mae runs a system called Condo Project Manager. Lenders log the review there. Fannie can set a project's status to Unavailable when it learns the project doesn't meet the Selling Guide, or when something else about the project worries it.

Once that status is on, no loan in that project can be sold to Fannie Mae. Not the well-qualified buyer. Not the owner refinancing. Not the unit at the far end of the corridor with a new kitchen. The flag sits on the project, not the unit.

Fannie's own guidance gives the common triggers. Budget reserves that fall short. Owners behind on their assessments. Repairs the association hasn't made.

Boards don't get a letter when it happens. Most find out when a sale falls apart in underwriting. That's interesting, and not in a good way.

And here's where it spreads.

Take a board that collects $400,000 a year in dues. Under the old rule it had to show $40,000 going into replacement reserves. Under the new one it has to show $60,000.

That $20,000 has to come from somewhere. Either dues go up, or something in the operating budget gets cut, or the project stops qualifying for conventional financing.

Boards cannot solve it with a special assessment either. Fannie's condo guidance says plainly that a special assessment can't stand in for the budgeted reserve allocation.

Now count the buildings. About 78.1 million Americans live in a community association, roughly one in four of us. Most boards approve one budget a year. For a lot of them the meeting that decides this is the next one on the calendar.

So a rule written in Washington in March turns into a dues increase voted on in a clubhouse in November.

Meanwhile, the same lender letter rewrote the insurance rules, and this half got even less attention.

For loan applications from July 1, a master property policy can carry a per-unit deductible of no more than $50,000. That number tells you what associations have been buying. Insurers took the premium down by pushing the first loss onto the owner.

There's a matching rule for the owner. If the master policy has a per-unit deductible, the borrower must carry their own unit policy, and it has to cover at least the amount of that deductible. The owner's own deductible is capped at the greater of 5% of coverage or $2,500.

Fannie loosened things elsewhere in the same letter. It dropped the inflation-guard requirement for projects. It also stopped requiring that roofs be insured on a replacement-cost basis, for houses and for condo buildings alike.

Read those together. The roof is the most expensive thing most associations will ever replace. It no longer has to be insured for what replacing it costs.

And the buyer who might absorb all this is borrowing at 6.54%, the average 30-year rate in July. That buyer is doing arithmetic on the dues, the deductible and the rate before they ever think about the view.

Three more things worth keeping track of this week.

The Netherlands is dismantling the biggest buyer of very long-dated European debt. Its pension system, about €1.6 trillion, is converting from defined benefit to defined contribution, and every fund must finish by January 2028. Roughly €600 billion of assets has already moved across, with more than €900 billion due early next year. Dutch funds held around €88 billion of interest-rate swaps maturing beyond 25 years at the end of last year, close to a quarter of that market. ING and PIMCO both expect the 30-year and 50-year end of the euro curve to lose its most reliable customer.

Memory chips keep getting more expensive for everyone who isn't buying them for a data centre. Conventional DRAM contract prices rose about 60% quarter on quarter in the second quarter, and TrendForce expects another 13% to 18% in the third. Samsung, SK hynix and Micron have pointed their advanced capacity at high-bandwidth memory for AI servers, which leaves the chips that go into laptops and phones short. Slower price rises this quarter are a demand story, not a supply one. Buyers stopped being able to pay.

Retail money keeps moving into structured credit. The largest AAA-rated CLO exchange-traded fund passed $30 billion in assets last month, with more than $5.7 billion of net inflows this year. Five years ago that market was institutions only, and the appeal now is a yield above cash with a ticker you can sell at 3pm. The tranches underneath it don't trade that way. We'll see.

Lenders love collateral they can touch. Steel in a yard. Grain in a silo. Oil in a tank.

In the early 1960s a former butcher from the Bronx named Anthony De Angelis ran a company in Bayonne, New Jersey called Allied Crude Vegetable Oil Refining. He stored soybean and cottonseed oil in tanks on the waterfront. A warehousing arm of American Express inspected those tanks and issued receipts stating how much oil sat inside. Banks and brokers lent against the receipts.

Vegetable oil floats on water.

De Angelis filled the tanks with seawater and poured a thin layer of oil across the top. An inspector who measured at the surface found oil. The receipt said the tank was full. Nobody drained one to check.

By late 1963 Allied had borrowed from 51 creditors, among them Bank of America, Chase Manhattan and Bank Leumi. The paperwork covered close to two billion pounds of oil. The tanks held about 110 million pounds.

He used the money to corner the soybean oil futures market. In mid-November the price fell instead of rising. The margin calls came. Then a nervous broker asked for all the tanks to be opened at once.

Allied filed for bankruptcy on November 19, 1963. Losses to banks and brokers came to about $150 million. Ira Haupt & Co., a respected Wall Street firm, could not cover its customers' positions and went under.

Every lender in the chain read the same receipt. It was accurate about the paperwork and wrong about the tank.

Warren Buffett looked at the wreckage, decided the card business underneath it was fine, and bought American Express.

The part that stays with me is that not one lender in that chain did anything unusual. They took a document from a professional third party and priced the loan off it. That is how almost all secured lending works, then and now.

I have no idea where today's version sits. But every lending market rests on somebody's inspection, and inspections get cheaper the longer nothing goes wrong.

Collateral is only worth as much as the last time somebody looked inside it.

We'll see.
