The few I have done have been isolated area's within the home from either a roof leak not taken care of or domestic water leak not taken care of.   

Everyone that does DDM th "standard way" has less than 1% success rate.

These fees include things like cable, water , trash , pool, fitness center.

Rates are a little higher than standard but origination and appraisal is easy.

Is it standard practice to do an inspection on wholesale deals? 

.- Water/ Sewer - Should be able to charge back to tenants.- Interest rate - Feds raised rates again, so might be tough to find a non owner occupied (assumed due to your location) conventional loan @ 5%.- Confirm property taxes on the county website.Feel free to PM me if you have questions. 

Water & Sewer: $0 (tenant pays in most cases right?)

Definitely have water heater/new roof/vacancy money set aside for it though. 

They certainly saw the rip in the screen, the holes in the walls during their inspection.Our lease has a clause to the effect that the tenant has inspected the property and is accepting it 'as is', EXCEPT for items that could not be observed during inspection, for example, water was off, so tenant could not see the faucet drip. 

You may want to try offering a Buyers home warranty so that the major issues in the property would be covered, foundation, appliances, water lines etc., for a mere $75 per event?
