How Rising Interest Rates Move Apartment Values

On September 16, the Federal Reserve raised its benchmark rate for the first time in three years, to a range of 3.75% to 4%. Within days, the 10-year Treasury pushed past 5%, its highest level since 2007. If you own apartments, you probably felt that headline in your stomach before you could explain it.

So let's explain it. There's a straight line from a Treasury yield in Washington to the price a buyer will pay for your building in Norwood or Kettering, and once you can see it, you can plan around it instead of guessing.

1.The Treasury sets the floor for your buyer's loan

Most apartment loans aren't priced off the Fed's overnight rate. They're priced off longer-term Treasury yields, usually the 5-year or 10-year, plus a spread for the lender's risk. On a stabilized agency loan, that spread commonly runs somewhere around 1.1 to 1.7 percentage points.

That's why the 10-year matters more to you than the Fed announcement itself. When the 10-year climbs from the mid-4s to above 5%, your buyer's mortgage rate climbs right along with it, whether or not the Fed ever moves again.

2.The loan rate feeds the cap rate

This is where it connects to value. In an earlier article, I walked through the band of investment, the method appraisers and disciplined buyers use to build a cap rate from the cost of the money used to buy a building. The short version: your cap rate is a blend of what the bank charges and what the buyer's own cash demands, weighted by how much of the purchase each one covers.

When the bank's side of that blend gets more expensive, the cap rate has to rise to cover it. And when the cap rate rises, the value of the same income falls.

Watch it happen to one building

Take a building producing $200,000 of net operating income. The buyer finances 70% of the price on a loan amortized over 25 years and wants an 8% cash return on the 30% they put in. Only one thing changes: the interest rate on the loan.

Apartment loans are pricing around 7% today. If your buyer could have borrowed at 6% not long ago, that one point costs the building roughly $160,000 of value, about 6%. Same tenants. Same rents. Same roof. The only thing that changed was the price of the money a buyer uses to pay you. And if rates drift toward 8%, it happens again.

3.Higher rates also shrink the loan itself

There's a second, quieter effect. Lenders don't just care about loan-to-value. They also require the building's income to cover the mortgage payment with room to spare, typically at least 1.25 times on agency debt. When rates rise, the same income supports a smaller payment, which means a smaller loan.

For a lot of deals, that's the constraint that actually bites. The buyer can't borrow as much as they planned, so they either bring more cash, which raises the return they demand on it, or they lower their offer. Either road leads to the same place: downward pressure on price.

Why values don't drop in a straight line

If the math were the whole story, every rate move would reprice every building instantly. It doesn't work that way, and it's worth knowing why.

• Buyers absorb some of it. When debt gets expensive, some buyers accept a thinner cash return rather than walk away, especially if they believe rents will keep growing. That cushions the cap rate move.
• Sellers wait. Owners who don't have to sell often simply don't. Fewer buildings trade, and the ones that do tend to be the strongest. In the short run, rising rates show up more in sales volume than in headline prices.
• The comps lag. Appraisals and broker opinions lean on recent sales, and recent sales reflect deals priced months ago. There's usually a gap between when rates move and when the evidence catches up.

So the numbers above aren't a prediction that your building just lost 6%. They show the pressure that's now pushing on pricing, and which direction the market has to go to clear.

What you can actually control

You can't control the 10-year Treasury. You can control more than you might think.

• Your NOI. Value is income divided by the cap rate, so income is still the biggest lever you hold. At the 8.3% cap rate in the example above, every $10,000 of added annual NOI adds about $120,000 of value. Closing a loss-to-lease gap or trimming a real expense can offset a surprising amount of rate pressure.
• Your existing loan. If you locked in low-rate agency debt a few years ago, that loan may be assumable, and in this market a below-market assumable loan is a genuine selling feature. Buyers will pay for it.
• Your financing options. When bank debt gets expensive, seller financing can bridge the gap between what a buyer can borrow and what your building is worth. I wrote about that in Become the Bank.
• Your timing, on purpose. Waiting for rates to fall is a bet, not a plan. They just went the other way. The better question is whether your building's income, your loan, and your goals make it smarter to sell into this market, hold through it, or refinance around it.
