Once seller receives inspection report, they should have to disclose it in the future if it's a material defect, so worth the attempt, at least, as seller should know the next offer will likely be lower, anyway, if they must disclose whatever major issues you found. 

The fact you had title insurance does not mean that the new owner will get it if the title agent finds a defect in the title your attorney didn't find.

if you received a title commitment it should have a requirement for a release or removal of whatever the defect is. 

If the current tenant is already there, they are living with whatever defects exist.

So if you find a property that you think makes sense, and you commit to it, you cannot get your EMD back if you back out later (eg, after your contractors points out some defects or costs that maybe you missed yourself). 

Last one must have been defective.******  Tenant says he was cleaning it and a hole broke thru,,,,must have been with a hammer and chisel. 

Do you (or anyone else here) have experience with having a property with some defect go through appraisal?

An inspector will be able to give you a an indication to age of systems and if any obvious defects are present, which you can use to possibly further negotiate a price.

My written rental criteria defect that.

He'll point out any defects in the foundation, plumbing, furnace, AC.
