What is my real monthly payment?
ChatGPT / General AI
Estimates principal + interest only. Forgets taxes, insurance, and PMI — the numbers that actually determine if you can afford it.
HomeRates.ai
Calculates full PITI — Principal, Interest, Taxes, Insurance, and PMI — using your actual numbers and live rates.
→ The difference can be $400–$800/mo on a $400k home.
What are mortgage rates today?
ChatGPT / General AI
Quotes rates from its training data — often 12–24 months out of date. Has no access to live market data.
HomeRates.ai
Pulls live rates from FRED (Freddie Mac weekly average) every time you ask. What you see is what the market actually says today.
→ A 1% rate difference on $400k = $240/mo and $86k over 30 years.
How much house can I afford?
ChatGPT / General AI
Uses national average rules of thumb. Does not know your DTI, debt load, or actual loan limits for 2026.
HomeRates.ai
Works backward from your income and debts using current DTI guidelines and 2026 conforming loan limits.
→ Generic rules can over- or underestimate your ceiling by $50–$100k.
Do I need PMI and when does it go away?
ChatGPT / General AI
Often confuses PMI (conventional) with MIP (FHA). Gets the cancellation rules wrong — a common source of misinformation.
HomeRates.ai
Knows the difference. Calculates your exact PMI cost, the LTV threshold to cancel it, and how long you'll pay it.
→ PMI is $100–$300/mo. Knowing when it ends changes your long-term plan.
Should I do 15-year or 30-year?
ChatGPT / General AI
Gives a general answer. Cannot show you a live side-by-side with your actual numbers and today's rates.
HomeRates.ai
Runs both scenarios with live rates and your loan amount. Shows monthly payment difference and total interest saved — your actual tradeoff.
→ 15yr saves $150k+ in interest but costs $600+/mo more. You need real numbers to decide.
Does this rental property cash flow? (DSCR)
ChatGPT / General AI
May not know current DSCR lender requirements. Will approximate — and get it wrong in ways that matter.
HomeRates.ai
Calculates DSCR ratio, monthly cash flow, and lender qualification using live rates and 2026 investor loan guidelines.
→ Wrong DSCR analysis on a $500k investment property is a very expensive mistake.
What are my total costs to close?
ChatGPT / General AI
Generic estimate. No awareness of your state, loan type, or current lender fee trends.
HomeRates.ai
Breaks down closing cost categories — origination, title, escrow, prepaid items — and what to expect based on your loan type.
→ Closing costs average $6,800. Being surprised by this at the table is avoidable.
