Your Investments Deserve
30+ Years of Experience
Daron R. Hays
I built my first house at 18. Construction and real estate investing have been part of my life ever since. Even after my engineering degree 10 years later, and working as a structural engineer, I was soon right back to doing what I love — construction and real estate investments. This is a passion of mine, and 100+ investments later, I believe that the best investments start with the best knowledge. This app was once a spreadsheet that I used myself and shared with family and friends, now this version is faster, easier to use with amazing charts and data — in seconds.

Built to Help You Succeed
The HomeFastCalc.com analysis engine was designed from decades of personal experience in real estate investments, engineering and construction — every important calculation and analysis for successful real estate investment provided in seconds.
HomeFastCalc.com exists to help you make the best possible informed real estate decisions, to help you avoid the bad deals, and profit from the good deals. It’s a professional-grade analysis platform, based on decades of real-world analysis. I built HomeFastCalc.com the way I build everything — with precision, transparency, and a focus on creating both short term and long-term value for you.
Get Professional Investor Analysis
My goal is to give you the best possible data and information possible, to help you make the best decisions possible. Why get outsmarted by a better-informed buyer or seller? HomeFastCalc.com gives you the same rigorous analysis used by professional investors — the same analysis I use for my own investments. Knowledge is power — use that power to negotiate better, get better financing, compare different deals with confidence, and sometimes, yes, to walk away from a deal that does not meet your investment standards. Ultimately this is a tool that can help you make better decisions, make better investments, and earn more profits.
