Real Estate and Stock Calculators

These are the five calculators I use while working on the articles. You can replace my sample figures with your own and watch the property value, loan coverage, hotel income, shopping-center value, or stock estimate update.

A note about the results

What the calculators can’t account for

A calculator can’t read a lease, inspect a roof, quote an insurance policy, or know what terms a lender will offer. The stock model also depends on estimates for earnings growth and the future P/E ratio, and both can turn out very differently.

I use these tools to compare possible outcomes. Before making a real investment, I would still need the original documents, several different estimates, and advice from qualified professionals.
