A good cap rate is relative to risk
A 9% cap rate looks great until you price in the higher vacancy, turnover, and maintenance of the markets that produce it. The better question is not which deal shows the highest cap rate, but which cap rate pays you fairly for the risk you are taking. A 5% cap in a prime market can beat an 8% cap in a declining one once you count repairs and empty months.
The 2026 catch
At a 6.8% mortgage rate, only 6 of the 18 metros we track run a positive cash-on-cash return on a 25% down purchase, and only 4 clear a lender's 1.2 DSCR. The split is geographic. The cheaper Midwest and Southern metros cash-flow, while the pricier coastal and Sun Belt metros do not. Cleveland clears the bar at a 7.2% cap rate with a 1.22 DSCR and +4.6% cash-on-cash, but Phoenix, at a 3.8% cap rate, runs roughly 7% in the red. A good cap rate on paper does not guarantee positive cash flow after financing, which is why the Index blends cap rate, yield, DSCR, and cash-on-cash instead of trusting any single number.
See the math at the cap rate formula, then compare it with cash-on-cash return.
