Proof of landlord liability policy (a must)!

Not water proof etc.

Some will want full tracing proof.

Depending on location (state) there are options for 80% cash out with no seasoning as long of proof of rehab is provided.

Also, if the Builder had to pull permits from the town, they may have had to show proof of insurance and that may be on file. 

Another unfortunate situation with a lot of these sorts of tenants is that they are "judgment proof", meaning, even if you were to sue them for damages, they do not make sufficient income or have sufficient assets to collect on your judgment.

They would have to have a compelling reason to do so like a fully executed purchase and sale agreement and proof of funds necessary to close.

The truth is that most agents are terrible, but you are likely not finding the good ones because you have a preconceived notion that they all suck.Some questions for you:If you are a cash buyer, did you show proof of funds to any of the agents? 

@Sunjeeve Weerasinghe we have moved entirly to vinyl plank in our properties (and so have a lot of major builders) as you can get commercial grade with 30+ year wear layers on them, they are water proof, do not chip (though they can be cut or torn) and are quite a bit cheaper than tile.
