The Real Estate Professor — Free Tools
Free Real Estate Calculators
Real numbers, plain language, no catch
Seven working tools, each wrapped in the judgment I'd give you across the kitchen table — because a calculator without context is just arithmetic. Every number here comes from thirty-plus years of remodeling, listing, and closing homes. Pick your tool:
Mortgage Calculator
The whole monthly payment — principal, interest, taxes, insurance, and PMI — plus how PMI fades away at 20% equity.
Commission Savings
The traditional commission versus the flat-fee route, side by side. The easy math the industry hopes you never run.
FSBO Net Proceeds
What you actually walk away with — payoff, transfer taxes, credits, and all — selling without a traditional agent.
Deal Analyzer
Total cost in, equity at ARV, margin, and the 70% rule — with a contractor's warnings about repair budgets.
Pre-Sale Repair Costs
Check off the work, total the honest prices, and sort every item onto the fix-freshen-or-credit ladder.
Builder Cost Calculator
Turn square footage, site work, allowances, contingency, and builder markup into a complete early-stage construction budget.
Real Estate Terms Wheel
Spin through buying, selling, contract, building, and investing terms — with the fine print translated into plain English.
Why these tools are different
Any site can host a calculator. What the generic ones can't give you is the line underneath the number — when a repair should become a credit at closing, why you search below your pre-approval instead of at it, and which bid deserves the hardest look. That's the part I've spent since 1988 learning, and it's built into every page here. The tools are free, no signup, no catch — because informed clients make the best clients, and some of you will want a pro in your corner when the real transaction starts.
