The price-to-rent ratio compares the cost of buying to the cost of renting the same home. A ratio below 15 generally favors buying; above 20 generally favors renting. At $475,000 with Detroit rents averaging $1,524/month, the ratio is 26× — which favors renting.
The 28% rule says your mortgage payment should not exceed 28% of your gross monthly income. To comfortably afford this home on a 30-year mortgage with 20% down, you would need to earn at least $112,759/year. Using the broader 36% total debt guideline, the minimum income drops to $87,701/year.
Rents in Detroit are up 3.8% year-over-year as of 2026-08. Rising rents shift the buy-vs-rent calculus — locking in a fixed mortgage payment provides certainty that a lease renewal cannot.
Inflation & Affordability in Detroit
Local consumer prices in the Detroit region have changed approximately 2.9% annually, based on the BLS CPI division covering this area. Over three years, that adds roughly $41,325 in cumulative inflation on a $475,000 purchase — a reminder that the money you spend today stretches further than that same amount will three years from now.
A 1 percentage point increase in the mortgage rate adds approximately $264/month to the payment on a $380,000 loan. When the Federal Reserve raises rates to fight inflation, mortgage affordability tightens quickly — even modest rate moves compound significantly over a 30-year loan.
The salary needed to comfortably afford this home ($112,759/year at the 28% rule) should also be compared against local wage growth. If wages are not keeping pace with both inflation and rising home prices, affordability deteriorates even when interest rates hold steady.
