Your screening should include a way to verify their identity, current employer, current residence, etc.

Everybody is mostly identical with settle differences, depending on niche your need is could help steer you towards a better fit. 

I'm guessing lots of landlords would be happy to upload these, and once a bunch are uploaded, the computer generated ones with copy-pasted identical signatures would start to stand out.

So although the QI and title company should have reflected the purchase identical to the sale, you and your partner may have issues down the road. 

A house on one street could be valued at 150k while an identical house one street over comes in at half that. 

This is a 2nd unit which is identical...

I was actually about to come to BP to post almost an identical topic except it is happening at my primary residence.

You could take two identical houses next to each other and run similar/exact spreedsheets for both of them, and they will perform differently, sometimes wildly.

Identical layout, wall-unit for A/C, super boxy cookie-cutter look, originally intended to be sold as a package deal of 5 properties (so it makes sense previous owner would slap down two manufactured homes for extra income), etc. 

say A and B are essentially identical neighboring properties but B has a 80% LTV mortgage on it so its costs are say 70% higher than A.
