Realtor Location Mortgage Calculator API

Supply homePrice, downPayment and location; optional rate, homeInsurance and hoaFees allow explicit scenario inputs. The documented location example is 11212, Brooklyn, NY. This version-1 calculation route was not live-tested, so output fields, implicit assumptions, rate units and insurance periods are unconfirmed. Inspect defaults and units before comparing scenarios, and do not assume the contract or calculations match the other mortgage routes. Treat outputs as illustrative budgeting estimates, not quotes, approvals or personalized financial advice.

API Features

Location-aware scenario request Required location accompanies homePrice and downPayment in this documented calculation input.

Optional financing assumptions rate, homeInsurance and hoaFees can be submitted to evaluate their effect on the calculation.

Version-one calculation contract This route has a distinct input set from version 2 and should not share an unverified output mapping.

Default-assumption inspection No calculation fields were confirmed; verify implicit costs, units and periods before using an estimate.

Frequently asked questions

What are the minimum inputs for the version-one mortgage calculation?

homePrice, downPayment and location are required. rate, homeInsurance and hoaFees are optional, but defaults and output behavior were not live-tested and need validation.

Are homeInsurance and hoaFees monthly or annual amounts?

That is unconfirmed for this operation. Verify accepted units and periods rather than importing assumptions from another calculator.

Does a calculated result represent approval or a lender quote?

No. Any available result is at most an illustrative budgeting estimate, not a binding quote, approval, qualification assessment or personalized financial advice.
