Investing in Grafton, WI — Market Analysis
Grafton is one of the lower-basis entry points in Wisconsin, with a median home price around $380,000. Grafton is a suburban growth market, which typically means single-family stock, longer average tenancies, school-district-driven demand, and lower turnover cost than urban infill. Suburban DSCR deals tend to underwrite cleanly because the rent comps are homogeneous.
Buying a rental property in Grafton on a DSCR loan means putting a minimum of $76,000 down (20% of purchase price), leaving a loan amount of $304,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $2,126 per month. Add Ozaukee County property taxes of roughly $510/month and landlord insurance of about $152/month, and your all-in PITIA lands near $2,787/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Grafton should generate roughly $1,975/month in gross rent. Against a PITIA of $2,787, that produces an estimated DSCR ratio of 0.71x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
Two Wisconsin-specific items to build into your model: Wisconsin funds schools heavily through property tax and levies are set locally each December, so effective rates in the Milwaukee and Madison suburbs are among the highest in the Midwest; northern lake counties also apply room tax to short-term rentals. In Grafton specifically, effective property tax on investment property runs around 1.61% of value annually — about $6,118 a year at the median price — and landlord insurance near $1,824 a year.
On return metrics, Grafton pencils to an estimated cap rate of 3.87% using a 62% NOI margin, and a gross rent multiplier of 16.0. Monthly cash flow on a long-term lease at 20% down is estimated at $812 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
