Frequently Asked Questions
How are Georgia property taxes estimated?
Georgia uses local millage rates and a 40% assessment ratio for most residential property. This calculator stores local property-tax rates as effective rates against home value so monthly escrow estimates remain easy to compare.
What Georgia closing taxes are included?
The estimate includes Georgia real estate transfer tax on the sale price and Georgia intangible recording tax on the mortgage amount.
Why include Cobb County?
Cobb captures high-volume Atlanta suburbs including Marietta, Smyrna, Kennesaw, and Acworth.
Does this mortgage calculator include taxes and insurance?
Yes. This calculator estimates your full monthly housing payment by combining principal and interest with property taxes, homeowners insurance, and PMI when your down payment is below 20%. The result reflects a PITI-style payment rather than principal and interest alone, which helps you compare homes and loan scenarios more realistically before talking to a lender.
When does PMI apply on a mortgage?
Private Mortgage Insurance (PMI) typically applies when your loan-to-value ratio exceeds 80%, meaning your down payment is less than 20% of the purchase price. PMI is usually added to the monthly payment until you reach sufficient equity. This calculator includes PMI in the estimate when your inputs trigger it, so you can see how a smaller down payment affects affordability.
