| Tool | Description | Behaviour |
|---|---|---|
| compare_zips | How do these zip codes compare as rental markets? Side-by-side comparison of 2-6 US zips: rent, cap-rate band (modeled), vacancy, home value, population, renter share, income, employment, with a doorbase.app link for each. | Read-only |
| get_zip_market | What does the rental market look like in this zip code? Full profile for a single US zip: rent, cap-rate band (modeled), vacancy, home value, demographics, income, employment, the county's HMDA mortgage lending conditions (purchase/refinance denial rate, median rate and loan, loan-type mix), plus the canonical doorbase.app page URL. | Read-only |
| hazard_risk | What flood, wildfire, and wind risk does this zip code carry? NFIP flood-insurance claims on record (count, payouts, recency, claims per 1,000 housing units), FEMA National Risk Index county scores for flood, wildfire, and wind, and recent significant storm events. Claims are history, not a forecast. | Read-only |
| rent_trend | Which way is rent moving in this zip code? Monthly median-rent history with home values, the direction of movement, and the zip's national and state rank for 3-month rent growth. Updated monthly. | Read-only |
| search_markets | Which US zip codes match these rental-market criteria? Filters 30,000+ US zip codes by state, cap rate, vacancy, rent, population, home value, and renter share. Returns matching zips with key investor metrics and a doorbase.app link for each. Cap rates are a modeled band; min_cap_rate matches the band's high end. | Read-only |
| top_markets | Which US rental markets look strongest right now? National (or single-state) leaderboard: zips with the highest estimated cap-rate bands among markets with population of 10,000+ and complete rent, vacancy, and home-value data. Cap rates are a modeled band. | Read-only |
