About
Closing costs represent the accumulation of fees required to finalize a real estate transaction, distinct from the down payment. While often estimated at 2% to 5% of the purchase price, the variance depends heavily on jurisdiction, loan product (FHA vs. Conventional), and the specific day of the month the transaction closes.
This estimator utilizes an advanced logic engine to account for variable factors such as Per Diem Interest, Transfer Tax Brackets (including "Mansion Taxes"), and Lender Escrow Reserves. It is designed to provide homebuyers and agents with a mathematically rigorous projection of the total liquidity (Ctotal) required at the settlement table.
