The 30% rule — spending no more than 30% of gross income on housing — is the most widely cited benchmark for affordability. On a $30K salary, 0 cities (0%) meet this threshold. That's a tough market. We ran the numbers on 2 cities in Kentucky using 2026 census, rent, and salary data. Louisville comes out on top — here's the full ranking and analysis.
Here's Louisville by the numbers — and there's a lot to like (and a little to watch). Cost index: 94. Rent: $1,352/month. Income: $64,731/year. Home price: $259,139. Population: 622,981. The strongest category is Housing at 84; the most expensive is Healthcare at 96. Translate that rent to annual numbers, and residents are saving renters $6,516 per year vs. the national median. That adds up much faster than people realize. If you've been scrolling through listings in high-cost metros and feeling defeated, look at these numbers again. Seriously. The difference between renting here and renting in a major coastal city could literally fund a retirement account. That's not hyperbole — run the math yourself. A thousand dollars a month saved, compounded over a decade, is a down payment on a house. In this city, that math actually works.
It checks most boxes — but the healthcare costs are the asterisk. In Louisville, the healthcare index sits at 96 — not a dealbreaker, but worth knowing about.
