How do I find the specific ID for a county to get its rent data?

First, use the `list_states` tool to get the state code, then use `list_counties` with that code. This will provide you with the 10-digit FIPS code (entity ID) needed for the `get_fmr_data` tool.

Can I retrieve rent data for an entire state at once?

Yes! Use the `get_state_fmr_data` tool and provide the two-letter state code (e.g., 'NY' for New York). It will return FMR data for all metro areas and counties within that state.

What is the difference between IL and MTSP data?

IL data (`get_il_data`) refers to general Income Limits for housing assistance, while MTSP data (`get_mtsp_il_data`) specifically targets Multifamily Tax Subsidy Projects. Both can be queried using the same entity IDs.
