The roof in this property is my main concern with it being slate and I noticed it had a couple of loose tiles.

People love following real estate investors and their progress, and you're bound to come across someone who wants to lend.

The market value at its current condition is 480k to 490k based on comps, which this person is in Florida and does not know this market,,, i Dont want to loose the deal, i even drove her to the airport so i can explained my offer in detail, BP WORLD, how could I counter this? 

Anyone offering FHA loans is bound by the same underwriting standards.

I think any loosely related degree will work (not something like anthropology, biology, etc. for instance).

The next problem is I hope there are enough comps in the area for an appraisal, and if not how much money do I loose chasing the deal.

This is literally how people "loose everything" in real estate.

Things are always bound to change overtime anyway.

Even if you self manage it and somehow get your expenses down to 35%, your still loosing -$83/month. 

Should an Unauthorized Occupant refuse to be bound by this Lease, or refuse to leave on our demand, as the case may be, you agree to pay, as Additional Rent, the sum of $20.00 for each day the Unauthorized Occupant remains on the Premises. 32.
