Underwriting — common questions
- Does Mortgage360 calculate GDS and TDS?
- Yes, on the deal itself, from the income, debts and property costs already on the record rather than from a separate spreadsheet. The inputs behind every ratio are stored with the result, so an underwriting decision can be re-examined months later.
- How does it handle the stress test?
- Qualification runs at the federal minimum qualifying rate as well as the contract rate, and both figures are shown side by side, so you can see immediately whether the stress test is what is limiting the deal.
- Can it underwrite business-for-self income?
- Yes. Self-employed income is modelled separately from salaried, with add-backs recorded as line items rather than folded into one number — which matters when a lender asks how you arrived at the income you submitted.
- Is the AI decision explainable?
- Every AI-assisted assessment stores the inputs it read and the reasoning it produced alongside the outcome. That is deliberate: an underwriting decision a regulator cannot follow is not usable, however good the recommendation was.
- Does it replace the lender's underwriting?
- No. It is broker-side underwriting — it tells you which deals will fly and where they will struggle before you submit. The lender's own adjudication is unchanged.
- Can I compare scenarios side by side?
- Yes. Rate, term, amortization, down payment and product can be varied across scenarios and compared in one view, so the conversation with a client is about a comparison rather than a sequence of recalculations.
