HUD subsidy contract expiry data for AI agents

Project-based subsidy contracts approaching their expiry date, queryable by state and window, free and without a key.

Short answer

Which HUD-subsidised properties have contracts approaching expiry? Yes, for 54 states and territories, effectively national. 4,721 published events. Free, with no API key and no signup. Call search_property_events at https://exchange-production-9123.up.railway.app/mcp.

What it returns

A dated contract expiry per property, with the property id, address, unit count and the programme record.

Coverage, with the denominators

Coverage is uneven by family and stating it any other way would be the one failure that matters here. These are whole populations, not samples.

Event family	Events	Where it is covered
SUBSIDY_CONTRACT_EXPIRING	4,721	54 states and territories, effectively national

Why this is different from the alternatives

An expiring contract is the point at which affordability is decided rather than assumed. Preservation buyers, state agencies and lenders all work this calendar and none of them can currently query it from an agent.

Where this does not help

Where it does not help

An expiry is a date on a contract. It is not a prediction that the owner will opt out.
Ownership is not attached: HUD publishes a management agent and never an owner.
