Missouri has a cost of living index of 89 (national average = 100). At 89, Missouri is a lower-cost state. Rents are comparatively high relative to home prices, which shortens the break-even timeline and makes buying more attractive at shorter time horizons than in pricier markets.
At a 3-year horizon, renting in Missouri is typically the lower-risk option because the buy premium of $332/month has not yet been offset by equity accumulation and appreciation. By year 4, cumulative equity growth and home appreciation generally surpass the total rent premium paid. Beyond 4 years, buying in Missouri historically delivers stronger financial outcomes for most households.
Missouri has a state income tax of 2%–4.95%. The mortgage interest deduction (federal) can reduce the effective cost of buying, particularly in the early years when interest makes up the bulk of your mortgage payment. Consult a tax professional to understand how Missouri's state tax rules interact with your overall housing deductions.
