Google Binns Genealogy which has a list of various VA counties having 18th century tax lists/tithables,personal property tax lists, etc. From time to time they have posted these lists as reconstructed census on varoots. 

I would think wills, inventories, settlements of estates if you can find them would be more detailed as what was on the various tracts.

One of the genealogy publishing companies has (don't remember which) has small booklets of the county tax lists for sale. I believe those lists are also at LVA.
