How this service works
Pay-per-call mortgage tools for AI real-estate and home-buying agents: monthly payment, affordability, and qualification against general agency guidelines. Educational estimates only — not a pre-approval, rate quote, or financial advice.
Output
Returns the loan-to-value ratio (LTV), front-end and back-end debt-to-income ratios, a boolean indicating whether the scenario falls within general agency guidelines, an array of explanatory notes, and an educational disclaimer. Does not include a rate quote, credit check, or pre-approval decision.
Example use cases
First-time buyer affordability check
“I make $78,000 a year and have $400 a month in existing debts. I'm looking at a $320,000 home with 5% down on a 30-year fixed at 7.1% — am I within normal mortgage qualifying guidelines and what would my front- and back-end DTI be?”
Investment property loan qualification
“I earn $140,000 annually and carry $1,200/month in debts. I want to take out a $500,000 loan on a 30-year term at 7.5% interest with 20% down — can you tell me my LTV, DTI ratios, and whether this fits general agency lending guidelines?”
Refinance scenario comparison
“I'm refinancing a $280,000 loan at 6.25% over 15 years. My annual income is $110,000 and I have $800 in monthly debts. What would my front-end and back-end DTI ratios be, and do I fall within standard qualification guidelines?”
Technical details
Endpoint
POSThttps://mortgage.homelending.online/qualifyWhen to prefer
Choose this endpoint when an AI agent needs a fast, low-cost educational estimate of mortgage affordability or qualification likelihood without connecting to a lender's live system. Ideal for real estate discovery flows, buyer pre-screening chatbots, or financial planning tools where a quick DTI and LTV sanity check is needed before deeper engagement. Not suitable when an actual pre-approval letter, credit pull, or rate lock is required.
Side effects
- Missing required fields (annual_income or interest_rate) returns a validation error
- Invalid numeric values (negative income, zero interest rate) may produce nonsensical outputs
- Highly unusual loan parameters may trigger notes warnings without a clear pass/fail
- Results are educational estimates only — not regulatory-compliant underwriting decisions
- Network or payment failure may prevent response delivery via x402 protocol
