Real Estate Math: In-Depth Guide for Florida
Real Estate Math is one of the highest-weighted exam topics and the one that causes the most anxiety for test-takers. The good news is that most real estate math uses basic arithmetic with a handful of standard formulas — no advanced mathematics required.
The most important formulas to memorize are: Commission = Sale Price × Rate, Cap Rate = NOI ÷ Value (or Value = NOI ÷ Cap Rate), GRM = Price ÷ Annual Gross Rent, LTV = Loan Amount ÷ Appraised Value, and Property Tax = Assessed Value × Tax Rate. The T-bar method (also called the "magic T") is your best friend for solving proportion problems — put the total on top and the two parts that multiply to equal it on the bottom.
Prorations at closing are frequently tested and require careful attention to dates and the direction of charges. Remember that the seller is responsible for costs through the day of closing and the buyer from the day after. Interest on mortgage loans is paid in arrears (for the previous month), while property taxes and HOA dues are typically paid in advance. Practice converting between annual, monthly, and daily amounts, and always double-check whether a question asks for monthly or annual figures.
