How do I run the numbers before I buy an investment property?

Running the numbers on an investment property starts with the purchase price and financing costs, not the advertised rent. Add taxes, insurance, HOA dues if any, and a maintenance reserve, then compare that total against realistic rent for the specific street, not a metro-wide average. Brian Beatty pulls comparable rents and recent closed sales so the math reflects the Lowcountry submarket you are buying into, and a lender or CPA should confirm the financing and tax assumptions before you make an offer.
