Assumes 3.0% annual rent growth, 2.5% expense growth, 3.0% appreciation, and a 6.0% selling cost at exit — all placeholder assumptions, not market-derived.
All figures are estimates for evaluation purposes only, not investment, tax, legal, or insurance advice. Property tax is estimated from a real matched tax bill or millage rate when available, a placeholder % of price otherwise; insurance is scaled by flood and wind risk where those are known and a flat percentage otherwise — never a real quote. Verify all of them, along with association restrictions and permit status, before committing capital. Rent estimates come from real comps or Zillow’s ZIP index, not appraisals.
