What this tool underwrites (like a lender)

Built for BRRRR and DSCR investors who want lender-aligned underwriting before they make an offer.
Capital$tack | Buy is a BRRRR calculator + DSCR underwriting tool in Google Sheets designed for lender-aligned rent, PITIA, NOI, Max Offer, and cashflow decisions.

  • Rent (Market + Underwritten Rent)
  • PITIA + cashflow modeling (post-refi)
  • NOI + DSCR outputs (lender-aligned)
  • Max Offer logic (negotiation-ready)
  • Suggested Opening Offer guidance
  • Primary Concern + verdict-style decision outputs
  • Deal Filter Mode so you can screen deals fast and skip dead deals early
How the spreadsheet actually works (the lender math)
Capital$tack | Buy underwrites your deal the way a conservative lender does, using rent, PITIA, NOI, and DSCR to decide if the numbers hold up before you make an offer.
  • Rent gets underwritten so the deal survives conservative assumptions.
  • PITIA is built like a bank payment so cashflow reflects real ownership costs.
  • NOI is calculated the correct way because lenders judge deals using NOI.
  • DSCR is measured against your target so the verdict matches lender thresholds.
  • Max Offer ties it together so you can pressure-test price + rehab without guessing.
Financing + refinance (to match your lender)
In the Financing Levers menu, you can model the deal the same way your lender will underwrite it. Finance and refinance paths are fully customizable.
  • Bank / Credit Union purchase
  • Hard Money / Bridge → Refi
  • DSCR lender purchase
  • Rate & Term refinance
  • Cash-Out refinance
✓ Run the same property through different paths and watch how your payment, PITIA, DSCR, and cashflow change in real time. Bottom line: you’re underwriting with your lender’s rules.
Best for
  • BRRRR investors (Buy, Rehab, Rent, Refi)
  • DSCR loan buyers
  • Rental property owners optimizing cashflow + DSCR
  • Conservative underwriting
  • Negotiation math + lender reality checks
