That information seals the deal.

I have couple of option:A) Hire a pest control company and takecare of the problem, they wouldcheck and seal all opening on roof, set traps and clean out attic to get rid of rodent scent and droppings and decontaminate if necessary.

As I'm doing more research regarding staining and sealing, I'm realizing these solutions don't last forever. 

At any time if they're worried about security, I will bring a new lockset in the sealed clamshell to the tenant's house, change out the lock, and hand them the keys.

Positive side sealing, and removal of the water (and the hydro static pressure on the walls) is by far the best long term solution. 

Do you really need to remove all the exterior paint and window trimmings for the FHA loan, or would sealing it under new paint suffice?

,one start:http://www.biggerpockets.com/renewsblog/2012/11/5/...also start with : cat odors or cat smell or cat urine in the forum search.but after you get rid of smell, you need to seal the concrete before anything else.also, 2 dozens of donuts, some sample pets treats and couple hours of chit-chat at the local pet-shelter will get you more info about what is used in commercial pet settings. also regulations....also don't forget to get friendly with the building neighbors...

Alexis W.Also, this is not legal advice, go find a competent FL Lawyer and get the record sealed/expunged.Witholding adjudication is a Florida specific thing and seems to mean you were never formally convicted, so it may not show up on a record beyond the arrest.

(You also don't have to use SIP roof panels with SIP construction.)I would also note that the SIPs create a very tightly sealed structure, so you are going to want to provide active ventilation such as an energy recovery ventilator.

The other posters had already convinced me to raise my price point in the house hunt, but you definitely sealed the deal.
