Realtor Mortgage Rate Scenarios API - Purchase and Refinance

Provide location and optionally loanType, loanTerm, propertyUse, propertyType, creditScore, points, showUsda and financing amounts. Documented loanType codes are 52 for purchase and 54 for refinance. purchasePrice and downPaymentPercent describe purchase inputs; propertyValue and loanBalance are documented for refinance. This route was not live-tested, so returned rate or offer fields, input dependencies and qualification behavior are unconfirmed. The documented showUsda toggle and rate term codes are request options, not proof of product availability. Validate code meanings and scenario handling, minimize personal-finance retention and treat any rates as nonbinding.

Frequently asked questions

Which amount inputs belong to purchase and refinance scenarios?

The documentation associates loanType=52 with purchasePrice and downPaymentPercent, and 54 with refinance propertyValue and loanBalance. Actual conditional dependencies were not verified and need testing.

Does showUsda guarantee USDA or FHA loan availability?

No. It is a documented program-selection input, not proof of product availability, borrower eligibility or a returned offer.

Is a rate returned after submitting creditScore a personal quote?

No. Score effects, qualification rules, rate fields and freshness are unconfirmed. Treat any available figures as nonbinding scenario references.
