A cleared owner will not stand next to a house they own
Clearance holders, federal contractors and households packing for a post abroad are a large part of this client base, and property records are public.
The proof this trade normally reaches for is an owner on camera saying the firm has been good to them. In the District, Arlington and Bethesda a lot of the people who would happily say it hold a security clearance, work for a federal contractor, or are about to leave the country for two years.
Put a name and a property in the same clip and you have published where somebody's family lives and attached it to an employer they are careful about naming. They will refer you privately and they will not be filmed, and asking a second time costs you the referral.
So the cast is your own staff. The maintenance coordinator who has opened every alley gate between Shaw and Petworth, the leasing agent who lists a garden level unit each spring, whoever explains an owner statement to a client reading it in another currency.
Written material follows the same rule. The question an owner asked is publishable. The owner, the block and the agency are not, and a caption saying a client at a federal agency has already narrowed it further than the client would like.
