That information may be online; Google [city or county] tax assessor--ie, Fairfax County Tax Assessor. The exact name may be somewhat different, but that search will usually get you to the right place. Even if you don't know the address, many tax offices have maps online, so you can identify the specific parcel (and other information) just by zooming in on the area.
I'd also try contacting the postmaster and the chief of police in the area. The postmaster probably could help; the police might, as well.
Good luck.
