Don Murphy is a real estate investor and researcher who builds and writes about practical tools for rental property investors. His focus is on DSCR loans, rental property underwriting, and the kinds of financial calculations that help investors stress-test a deal before speaking with a lender.

What I Do

I create free calculators and educational guides that explain real estate finance in plain language. Every article and tool is designed to help investors understand the assumptions behind the numbers, not to replace advice from a licensed mortgage professional, CPA, or attorney.

Experience and Approach

  • Active real estate investor with hands-on experience evaluating rental properties
  • Researches DSCR qualification thresholds, lender overlays, and rental property underwriting
  • Builds calculators that show formulas and assumptions transparently
  • Writes educational content with clear disclaimers and source notes

Important Disclaimers

I am not a licensed mortgage broker, CPA, financial advisor, or attorney. The content on DSCRFormulas.com is educational and should not be considered professional advice. Always confirm loan terms, qualification requirements, and tax treatment with qualified professionals who understand your specific situation.
