Evaluate a Mortgage with Explicit Cost Inputs
View All Realtor Property Data APIs →Provide price, term, downPayment, rate, propertyTaxRate and homeInsurance; applyVeteransBenefits is optional. These are the documented version-2 numeric inputs. Example rate and tax values use fractional-looking numbers, but their accepted scale and insurance period were not live-validated. No response fields or calculation behavior were confirmed for this endpoint. Verify every unit and optional benefit assumption before comparing scenarios; outputs must remain illustrative estimates rather than financing offers, eligibility decisions or preapproval.

Frequently asked questions
Should the interest rate be 6.6 or 0.066?
The documented examples appear fractional, but accepted scale was not live-verified. Validate ranges and calculation behavior on this operation instead of borrowing another calculator conventions.
Does applyVeteransBenefits=true establish benefit eligibility?
No. It is an optional request flag whose effect and qualification rules were not verified. It is not a benefits or loan-eligibility determination.
Can I replace version one with version two without changing inputs or parsing?
Do not assume compatibility. Version two has distinct explicit price, term and tax inputs. Validate its response and calculations independently before replacing a client.
