Due diligence often gets boiled down to some checklist of items folks seem to think they need to do.  

@Vick Galu  There are certainly some items that are negotiable regarding closing costs...however, lenders can have restrictions on what would be considered an "allowable" cost that is negotiable.  

If one uses realtors to sell, pays closing costs of all parties to buy, has hard money costs, and holding costs they typically make 10% profit on the sale.There is and can not be a new model of 80% for a rehab flip when the economics simply dictate there is no profit left for the actual party that takes possession, risks money, risks loss, risks vandalism, pays for insurance, has holding costs and actually adds value to the property through repairs.  

That could be the wholesaling model, or anything else out there. 

Misc extra rehab items that you didn't think about.

People go in asking for and expecting $100 for an item, but if they're are desperate, they leave with $10 or $20... 

@Troy Norwood every niche can be profitable, just make sure research and model those that have done it before you.
