My theory is almost identical to yours; 25% + returns, even if vacant for 3+ months per year are still much more profitable than an 8-10% return in a b class neighborhood that's tenanted all year.

The rest will have to be torn down.I'm looking to build an identical building addition with a entry way in the middle to make these into apartments due to the lot size.

For my home it is currently 100% accurate because I live in a townhome with 50+ identical units around me that sell 1-3 a month.  

My questions are as follows: how do I verify their identity?

What are people so scared of/trying to hide that they feel it's necessary to disguise their identity?

The two may even look identical.

2 duplexes for 162kZillow estimates they are worth 84k and 85k eachThey are both mostly brick, identical, and right next door to each other.

If you paid 100k and put in $50k and the identical house next door sold for $200k you'd likely still come in at 150kOn my last deal I told him I wasn't going to give him my sales contract.

He didn't have any proof of identity.

@Peter Sik your PM is probably using a property management software program to process this echeck. echeck's are essentially identical to ACH payments and are super secure.
