Buying a rental property in Louisville is a numbers game before it's anything else. This free investment property analyzer runs the numbers real investors actually use — cap rate, cash-on-cash return, net operating income, and monthly cash flow — so you know whether a deal pencils out before you write an offer.

How to read these numbers
Net operating income (NOI) is what the property earns after operating expenses but before debt service — it's the number lenders and appraisers use to value income property, independent of how you finance it.
Cap rate (NOI ÷ purchase price) lets you compare properties of different sizes and prices on equal footing. In the Louisville metro, cap rates on stabilized single-family and small multifamily rentals have generally run in the mid-single digits, though it varies block by block — use this calculator on a specific address rather than a neighborhood average.
Cash-on-cash return (annual cash flow ÷ total cash invested) is the metric most buy-and-hold investors care about most, because it measures the actual return on the money you put down, not the full purchase price. It's more useful than cap rate once financing enters the picture, since leverage changes your cash return without changing the property's underlying NOI.
Cash flow is simply what's left every month after the mortgage, taxes, insurance, HOA, management, and a maintenance reserve are paid. Positive cash flow on day one gives you a margin of safety for vacancy, repairs, and rate changes.
Why run the numbers before you tour the house
Louisville's rental market rewards investors who underwrite before they fall in love with a property. A house that looks like a great deal on a listing photo can turn into negative cash flow once real property taxes, a realistic vacancy allowance, and a maintenance reserve are added in. Running every property through the same calculator keeps your comparisons honest and helps you walk away from deals that don't work, fast.
Winner Realty works with buy-and-hold investors, house hackers, and small landlords across Louisville and the surrounding Kentucky and Southern Indiana submarkets. We can pull comparable rents, recent sale comps, and neighborhood-level tax and insurance figures so the numbers you run here reflect the actual market, not a rule of thumb.
Frequently asked questions
What's a good cap rate for a Louisville rental property?
There's no single "good" number — it depends on the neighborhood, property condition, and how much risk you're taking on. Class A neighborhoods in Louisville tend to trade at lower cap rates with steadier appreciation and lower vacancy; higher cap rates further out usually come with more management intensity or turnover. Compare a specific property's cap rate to other properties in the same submarket rather than to a national average.
Does this calculator include property management if I plan to self-manage?
The property management field defaults to 8% of rent, which is a typical local third-party management fee. If you plan to self-manage, you can set it to 0% — just remember your own time has a cost even when it isn't a cash expense.
Why is cash-on-cash return different from cap rate?
Cap rate looks at the property's return as if you paid all cash. Cash-on-cash return looks at your actual return on the cash you invested, after the mortgage payment is subtracted. A leveraged deal can have a lower cap rate but a higher cash-on-cash return, or vice versa, depending on your interest rate and down payment.
What maintenance reserve should I budget?
A common starting point is 5–10% of monthly rent set aside for ongoing maintenance and future capital items like a roof or HVAC replacement, adjusted for the age and condition of the property. Older homes or those with deferred maintenance should be budgeted toward the higher end.
