## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sindri-cap-rate-multi-year-real-estate-deal-analyzer-bac53189 -d '<json body>'
```

Example prompt: Can you run a full cap rate and deal analysis on a rental property I'm looking at — $425,000 purchase price, $2,400/month rent, 25% down payment, 7.1% interest rate on a 30-year loan, $5,200/year in property taxes, $1,800/year insurance, $2,500/year maintenance, 8% vacancy, $150/month HOA, and I plan to hold it for 7 years then sell for $550,000?

## When to prefer this

Choose this endpoint when you need a comprehensive real estate investment analysis that goes beyond a simple cap rate — specifically when you want multi-year cash flow projections, IRR, sale scenario modeling, and per-category growth rates for rent and expenses. Ideal for pre-purchase underwriting of residential rental properties or small multifamily deals.

## Known failure modes

- Missing required fields (purchasePrice, monthlyRent, downPaymentPercent, interestRate, loanTermYears, holdingLengthYears, annualPropertyTaxes, annualInsurance, annualMaintenance) returns a validation error
- Invalid fractions outside 0-1 range for rates return an error
- loanTermYears or holdingLengthYears outside 1-50 range rejected
- salePrice not provided may cause sale-scenario computation to fail or be omitted
- Negative expense or income values may produce nonsensical results

## How this service works

Cap rate calculator for real estate investing. Runs a full multi-year deal analysis (per-category rent/expense growth, a sale scenario, IRR) and headlines the capitalization rate: first-year NOI divided by purchase price.

## Output

Returns the first-year capitalization rate (NOI ÷ purchase price), first-year net operating income, mortgage payment, year-by-year cash flow projections with per-category rent and expense growth applied, net sale proceeds after costs, total holding period return, cash-on-cash return, and IRR over the specified holding period.
