LIHTC Year 15 and compliance-period data for AI agents

The Year 15 recapitalisation trigger, as dated events an agent can query by state and window. This is the broadest family DFX holds and it is free.

Short answer

Which LIHTC properties are reaching the end of a compliance period? Yes, for 56 states and territories, effectively national. 13,549 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 compliance-period ending per property, with the property's canonical id, address, unit count and the programme record it derives from.

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.

Why this is different from the alternatives

Year 15 is a transaction trigger, not a lookup: it is the moment a limited partner can exit and the deal has to be resyndicated, sold or refinanced. It is broadly published in bulk and almost never published callable.

Where this does not help

Where it does not help

Compliance periods are statutory and every one falls on 31 December, so a count bucketed by day shows a December cliff that is an artefact of the statute rather than a market event.
The event is the date the compliance period ends. It is not a statement that the property is for sale.
