Thieves are greedy and don't care where the $ comes from. 

Even if someone has built the exact same house you want on an identical lot in the same neighborhood, your cost is still going to be highly dependent on lots of things:-  Do you hire a builders or do it yourself?

I think a majority of them are thieves and thrive on nativity.

I own and live in the identical 4 plex right next to this one.Well one of the tenants in the building built a deck in the back yard.

The unit next door is in great shape/move-in ready, and is in escrow for $420k; identical floor plan and space.  

I'd add that a prospective tenant can fake anything, including the social security number and identity they are applying under, but forgery is a pretty serious crime to commit against someone who will literally know where you live.

I've seen peoples' lives temporarily ruined by identity theft and do not want to fall victim to this man.As to the tenant who showed me the house, he was not "Rob."

I staged it and sold it in a week (with 2 other identical units that had been on the market over a month).

Found the deal by picking up the phone and talking to an agent about a current listing.Best part is offer was accepted at $290K and an identical unit just hit the MLS at $360K. 

So, Why are they hiding their identity?
