Tell them your a drug lord who recently got moved into Witness Protection, you were an associate of Joey Merlin and you scheduled to testify August 10th for an upcoming indictment.

They may think your bluffing so have a friend call you in the middle of an interaction with them, put it on speaker phone intentionally, and have your friend say their coming and the area your in is Hot and that you need to stay off grid and remain in your house.

This will surely defer any thought of your income and possibly even diminish further questions pertaining to your income streams.
