## How to call it through Zero

```sh
zero fetch --capability proppulse-investment-property-analysis-0b9a8183
```

Example prompt: Can you run an investment property analysis on 4521 Oak Street, Austin TX — asking price $385,000, expected monthly rent $2,800, and I'd be putting 20% down with a 7.1% mortgage rate? I want to see the cap rate, cash-on-cash return, 5-year projection, and the investment grade.

## When to prefer this

Use this endpoint when you need a comprehensive investment-focused analysis of a rental or income-producing property, particularly when you need cap rate, cash-on-cash return, and a multi-year projection in a single call. Prefer this over generic property valuation endpoints when the user's goal is evaluating ROI and investment viability rather than market value or affordability.

## Known failure modes

- Missing or invalid property price returns a 400 error
- Invalid or missing rental income data causes computation failure
- Insufficient financing parameters may prevent cash-on-cash calculation
- Payment not processed returns a 402 Payment Required error
- Malformed address or unsupported property type may return an error

## How this service works

Rental property investment analysis and cap rate calculator: cap rate, cash-on-cash return, gross rent multiplier, annual NOI, break-even occupancy, 5-year appreciation projection, and investment grade for any rental property. For real-estate-investor agents.

## Output

Returns a structured analysis including the property's cap rate (net operating income / property value), cash-on-cash return (annual pre-tax cash flow / total cash invested), a 5-year financial projection showing cumulative returns and equity build, and an overall investment grade rating summarizing whether the property is a strong, moderate, or weak investment opportunity.
