What kind of a shelter would even request such a document or letter .

From those who have successfully invested in the Orlando area, what kind or percentages are you seeing (if you don't mind sharing)?

Hundreds of holes in the wall, filthy carpet, leaking roof and number of different kind of modifications on flooring.

Yup, it is a very common thing that is occurring. 

Not all lenders are into this kind of play, and you would want to make sure you could get your cash back after completing the value add.

As far as capital to get started, after you've exhausted the VA loan, the typical and common answer for a primary residence is a 20% down payment with a credit score and cash reserves good enough to qualify for a mortgage.

I was going to IRRL anyway, so it kind of just made sense.

Also you have mentioned all kinds of restrictions and set backs such as hurricanes and so... since we are talking about flipping and not buy and hold, do you still think those will have the same significance? 

what kind of strategy are you thinking?

I've used the strategies others have mentioned with success:Ultrasonic repellant devices (spaced every 20' or so if you can)Bounce fabric softener sheetsSteel wool and/or expanding foam in every crack and crevice that makes sense.If your cleaners aren't arriving right away, you will need someone to do a "check out" procedure after guests leave, to make sure the trash is immediately taken out, and no food of any kind is present, wipe countertops, etc.
