What the result means
Use Estimated affordable home price as the headline answer for house affordability. Highest home price that fits the selected ratio and cost assumptions. Read the main estimate first, then compare it with the assumptions and secondary outputs before using it in a decision. Use estimated monthly housing payment, limiting ratio, and estimated loan amount to explain why estimated affordable home price moved when an input changed. Compare the result with the source document or quote that will actually govern the decision.
