A portfolio of rental properties needs active market monitoring — not just property-level accounting. ZIP-code market data tells you where your holdings are positioned in the market cycle and flags properties ready for sale, refinance, or reinvestment.

Rebalancing Signals

Sell signal: A property in a ZIP code where market temperature is "hot," YoY price change >8%, and your current yield has compressed below 4% due to appreciation. The equity may be better deployed in a higher-yield market.
Hold signal: Market temperature is "warm," yield is above 5.5%, and HAI is trending up (market becoming more affordable relative to incomes) — good long-term hold conditions.
Buy signal: Market transitioning from "cool" to "warm," YoY change moving from negative to positive, DOM falling — classic early expansion entry.
