Confirm the contract

Ask for recorded contract documents and assessor confirmation. Map layers can flag probable enrollment; the record controls.

Compatible uses

Residences and agritourism may be limited. Compatible-use findings are local.

Exit paths

Nonrenewal and cancellation are slow or costly. Do not underwrite a deal on easy exit.
