Methodology

Medians are drawn from the latest available Zillow ZHVI/ZORI feed for FIPS 41051. The modeled deal assumes 20% down, a 3% closing cost, a 30-year conventional at 7.50%, and total operating expenses at 35% of gross rent (property tax, insurance, management, maintenance and vacancy combined). Cap rate is NOI over purchase price; cash-on-cash is annual pre-tax cash flow over cash in. These are portfolio-level baselines — actual listings will vary above and below.
