ChatGPTApp
Sumline helps real estate professionals get reliable property numbers inside ChatGPT without having to teach the AI how to calculate each scenario. Ask naturally about seller net proceeds, buyer cash to close and monthly housing costs, rental property returns, or fixed-rate mortgage payments. Sumline runs the same deterministic calculation engines used by the Sumline web app and returns the verified figures, assumptions, warnings, and a link to continue the scenario in Sumline. Sumline does not determine loan qualification or affordability and does not provide legal, tax, lending, appraisal, or investment advice.
