Take for example 2 hones with identical size and bed/bath counts.

Criminals use it to steal your identity.

The monthly payment was identical to 5% down due to rate differences.

If the tax assessed owner died, it can be tricky figuring out the identity of the legal heirs.3.

Was it identity theft?

The trustee's identity is pubic knowledge.

The house looks and like a duplex, has two identical sides (2 br / 1 ba ea).

The tax implications between the LLC and the S Corp would be pretty much identical and with an S Corp you would have to pay yourself a salary, file payroll returns, W2's, etc.  

I sold a lot in 2008, and then sold the identical lot next door in 2013 for 60% LESS.
