Buying a rental in Southeast Wisconsin: what gross yields actually look like

July 2026 · Guide · 3 min read · by Kinan Sawar, MD — REALTOR® at Shorewest, REALTORS®

The region's median gross rent yield is 4.72%. What that number includes, what it leaves out, and how the math changes with a 6.9% mortgage. Not investment advice.

What gross yield is — and the region's number

Gross rent yield is one year of rent divided by the purchase price. No expenses, no financing — just rent over price. Across Southeast Wisconsin's municipalities, the median gross rent yield is 4.72% as of April 30, 2026.

In plain terms: at a 4.72% gross yield, a $250,000 property would collect about $11,800 in rent per year, or roughly $983 per month. That is the top-line number before a single expense is paid.

Milwaukee County's math runs higher

Milwaukee County's typical rent is $1,516 per month against a typical home value of $288,774. That is $18,192 in annual rent divided by $288,774 — a gross yield of about 6.3%, well above the regional municipal median of 4.72%.

The pattern is structural: lower-priced markets tend to collect more rent per dollar of purchase price. And because 4.72% is a median, half of the region's municipalities gross less than that. The high-value municipalities in the dataset — Delafield at $757,187, River Hills at $960,523, Oconomowoc Lake at $2,005,472 — cost far more per door, and rent rarely scales one-for-one with price.

What gross yield leaves out

Two costs are easy to estimate from the data: property tax at roughly 1.1% of value per year and insurance at roughly 0.55%. Together that is 1.65% of value, every year, before anything else. On the Milwaukee County typical value of $288,774, that is about $3,177 in tax and $1,588 in insurance — $4,765 per year, or roughly 26% of the $18,192 gross rent.

Subtract just those two items and the county's 6.3% gross becomes roughly 4.65%. Apply the same 1.65% to the regional median of 4.72% and you are near 3.07% — before vacancy, maintenance, management, and capital repairs, none of which are in these figures. Gross yield is a screening number, not a return.

The financing reality at 6.9%

Now add a mortgage. At 6.9% with 20% down, the all-in monthly cost (principal, interest, tax, insurance) on the county's typical $288,774 home is roughly $1,919. Typical rent is $1,516. That is about a $400 monthly gap before vacancy, maintenance, or management — the property does not carry itself at these assumptions.

A larger down payment, a lower purchase price, a higher-rent unit, or a different rate all change that arithmetic. The point is not that rentals do or do not work here; it is that the current rate environment makes the spreadsheet mandatory. Run the numbers on the specific property, not on averages.

The trade-off the data cannot settle

Higher gross yield is not automatically better. The yield number says nothing about appreciation, property condition, turnover costs, or your tax situation — and lower-yield, higher-price municipalities may suit a different strategy than higher-yield ones. These figures are a snapshot as of April 30, 2026, and past figures do not guarantee future results.

This guide is general information, not investment, tax, or legal advice. Before buying a rental, talk to a licensed lender about financing, and a CPA or financial advisor about how a property fits your situation.

Southeast Wisconsin's median municipal gross rent yield is 4.72%; Milwaukee County's typical rent and value pencil to about 6.3%. But tax and insurance alone run about 1.65% of value per year, and at 6.9% with 20% down the typical county home costs roughly $400 more per month than it rents for. Screen with gross yield — decide with a full expense-and-financing spreadsheet and licensed professional advice.
