About Real Estate Calc Pro

Real Estate Calc Pro was built for buyers, sellers, investors, and renters who want to run the numbers themselves before trusting anyone else's math. Real estate is the largest financial transaction most people ever make, and the calculations involved — mortgage payments, closing costs, return on investment, rent vs. buy breakeven — are well within reach of anyone who understands the inputs. Our goal is to make that math fast, transparent, and free.

About the Author: Nathan Briggs

Nathan Briggs spent twelve years working in residential real estate as a licensed buyer's agent, transaction coordinator, and eventually a property investor managing a small portfolio of rental units in the Southeast. He has closed deals ranging from first-time buyer purchases under $150,000 to investment property acquisitions requiring complex financing structures.

Nathan became a writer after noticing that most real estate content online was produced either by agents with a transaction incentive or by publications that oversimplified complex financial concepts to make them accessible. He set out to create tools that were both genuinely accurate and genuinely free from sales pressure — calculators built by someone who has actually been on both sides of a real estate table.

He holds a real estate license and a bachelor's degree in Finance from Auburn University. His analysis of mortgage rate trends and regional market conditions has appeared in several independent real estate research publications. Nathan is based in Atlanta, Georgia, where he continues to manage rental properties and monitor local market conditions firsthand.

“Real estate wealth is built on understanding the numbers before you sign anything. The calculations are not complicated — they just take time to explain properly.” — Nathan Briggs
