HouseCanary

Where HouseCanary earns its money is granularity. Most valuation vendors hand you metro averages and call it a forecast; HouseCanary goes down to the block and ZIP, which is the difference between a number you can underwrite and a number you have to second-guess. We'd reach for this when the property is expensive enough that a metro-level comp set starts producing valuations nobody trusts. Who it fits: single-family rental operators screening dozens of markets, lenders that need AVM output inside an origination or underwriting flow, and capital markets teams doing pre-bid diligence on whole loan portfolios. Agents get a specific deal too — verified agents can lock in unlimited CMAs and propensity-to-list data on the agent plan starting at $19/mo. The MCP server is the sleeper feature. 149 property tools callable by an AI agent means you can build property research that runs itself — pull valuations, market data, and property facts inside a workflow instead of a browser tab. If your team already automates research, that shortens the loop considerably. Where it bites: the tier math. Teams gives you 10 active users and 40 custom valuation reports a month — if your analysts burn through reports faster than that, overages stack on top of the $165.83/mo effective annual price. Pro is one seat, so a two-person shop pays twice. Pass on this if you're a casual buyer, a flipper wanting free lookups, or a DIY landlord with a handful of doors. PropStream and similar tools fit a smaller budget, and the block-level data advantage doesn't show up when you're valuing one modest house. Closest thing to compare: the API. Pro and above include access to HouseCanary's core API, with usage-based costs beyond quota; Enterprise adds advanced APIs and custom datasets. Heavy programmatic
