## How to call it through Zero

```sh
zero fetch --capability proppulse-refinance-analysis-737400fb
```

Example prompt: Can you run a refinance analysis for my home — I currently have a $420,000 balance at 7.25% with 25 years left, and I can refinance to 6.5% on a new 30-year fixed with $6,000 in closing costs? I also want to see what a $50,000 cash-out option would look like.

## When to prefer this

Use this endpoint when a user wants a quantitative refinance decision framework — specifically break-even analysis, savings projections, and cash-out evaluation in a single call. Prefer this over generic mortgage calculators when the user needs rate timing context alongside the math.

## Known failure modes

- Missing required mortgage parameters returns 400 with field validation errors
- Invalid rate values (e.g. negative or >100%) return validation error
- Property value below loan balance triggers LTV warning or error
- Malformed numeric inputs return parsing error
- Service unavailability returns 503

## How this service works

Mortgage refinance calculator: break-even timeline, monthly and lifetime savings, cash-out refinance availability, new-rate estimate, and rate-timing guidance for any current loan. For homeowner and mortgage agents.

## Output

Returns a structured refinance analysis including the break-even month/timeline (how long to recoup closing costs), total interest savings over the loan life, monthly payment comparison, cash-out scenario details if requested, and guidance on whether current rate conditions favor acting now or waiting
