Real estate investors analyze dozens of properties before buying. A spreadsheet that instantly calculates cap rate, cash-on-cash return, IRR, and cash flow from basic inputs saves hours per deal and helps avoid costly mistakes.
Create 'The Real Estate Deal Analyzer.' Input: purchase price, down payment, loan terms, rent, expenses. Auto-calculates: cap rate, cash-on-cash return, IRR, NOI, debt service coverage ratio, and 10-year cash flow projection. Includes sensitivity analysis (what if rent drops 10%?). Price $29–59.
  • Include LOCALIZED expense assumptions — property taxes, insurance, and maintenance vary wildly by market
  • Add 'BRRRR Method' specific tabs (Buy, Rehab, Rent, Refinance, Repeat) — this strategy is huge in the RE investing community
  • Partner with real estate investing communities (BiggerPockets, local REIA groups) for distribution
