HOW THE DEAL SCORE WORKS
There is no black box. The score is a weighted average of five components - IRR, cash-on-cash return, DSCR, cap rate, and rent-to-price ratio - each scored on a published curve, then combined and mapped to a verdict band. The full method is documented at homefastcalc.com/methodology.

QUESTIONS PEOPLE ASK
Is anything held back? No. Every metric, every projection, and the PDF report are included.
Do I need an account? No. There is no sign-up and no login.
Do you store my property numbers? No. Inputs are processed to produce your results and your report, then discarded. Nothing about the property is saved.
What about my email? An email address is used to deliver your PDF report and is stored for that purpose only.
Does it work outside the United States? Estimates for tax, insurance, and rent use United States data. The calculator itself works with any numbers you enter.

PRIVACY
Property details are never stored - not the address, not the asking number, not the rent. Read the full policy at homefastcalc.com/privacy.
