One ratio — annual rent divided by price — quietly separates the cash-flow markets from the appreciation bets.
Two markets can have identical home prices and completely different investment math. The number that separates them is the gross rent yield: a year of rent divided by the purchase price.
A $250K home renting for $1,800 a month grosses about $21,600 a year — roughly an 8.6% gross yield. The same $1,800 rent on a $600K home is a 3.6% yield. Higher yields mean the property pays for more of itself from day one; lower yields mean you’re betting more on appreciation and tax treatment than on monthly cash flow.
Yields run highest in lower-priced, steady-rent metros — much of the Midwest and parts of the South — and lowest on the expensive coasts, where prices have far outrun rents. Milwaukee’s ZIP codes, for instance, generally pencil out in the mid-single digits, which is why the metro draws cash-flow-focused investors.
Gross yield ignores taxes, insurance, vacancy, and maintenance — all of which bite harder in some markets than others. Treat it as a first screen, not a verdict: it tells you which markets are even worth underwriting for cash flow. The ZIP table on each county view carries rent and an implied yield to get you started.
