Can AI replace Mortgage Coach?

The math here is not exotic: amortization schedules, PMI drop-off, points breakeven, net cost after N years, rent versus buy. An agent can build a clean side-by-side scenario comparator with charts and a printable one-pager in a single session, and for a person modeling their own refinance that is genuinely enough. What you cannot one-shot is the part that makes it a business tool: pulling live loan scenarios out of the LOS or pricing engine, compliance-reviewable output your employer will actually let you send to a borrower, and the delivery layer that tracks whether the client opened the presentation. If you are a licensed originator, your DIY version is a scratchpad, not something you put in front of a client. If you are the borrower trying to sanity check what your lender sent you, the DIY version is arguably better because you control the assumptions.

02Could AI build it for you?

The core job: Enter two to four loan scenarios, get amortization schedules, breakeven points and total-cost-over-time charts side by side, then print a one-page summary.

What a working version needs:

  • Node 20+
  • a browser
  • nothing else: no accounts, no API keys, all math runs locally

Great DIY tool for the person taking the loan, mediocre DIY tool for the person selling it.

03What you'd give up

  • Integrations with loan origination systems, pricing engines and CRMs, so every scenario is typed in by hand
  • Compliance-vetted presentation output and audit trail, which is the entire reason a regulated lender licenses this instead of using a spreadsheet
  • Borrower engagement tracking: who opened the presentation, how long they looked, which option they clicked
  • Polished branded video and mobile presentation formats that agents and borrowers are used to receiving
  • Someone else maintaining the edge cases: ARMs, buydowns, MI structures, state-specific cost lines

Loan officers do not buy this to do arithmetic, they buy it because it turns a rate quote into a story a borrower can act on, and because the output is something their compliance department has already approved for client delivery. The tool also sits inside the workflow: scenarios flow in from the origination and pricing systems, presentations go out through the CRM, and engagement comes back as a lead signal. A self-built comparator gives you the numbers but none of that plumbing, and in a regulated sales process the plumbing is the product.
