Yes, Aaron is correct, these are the very things that any appraiser would frown on. An FHA appraisal is more stringent because the lender has a higher stake in the loan, meaning, you're only putting 3.5% in yourself, so they have more liability in the property, and that it's a government secured loan.
A 203K loan is not any harder to obtain. There are $15,000 and $35,000 limits on how much you can receive (I may be wrong about those amounts). This amount is added to your mortgage. So, if the house is $100K, it's my understanding that an appraisal would be done to determine a value before and after the fix-ups and your mortgage amount would be based on the value AFTER the fix-ups have been done. The fix-up money is held by your title company and disbursed when the work is completed. The work must be done by licensed contractors. I'm not a lender, so my knowledge about these details is a little sketchy!
Hopefully, some lenders that are more well versed than I on the 203K will chime in here!
