However, this is just procedural, and I'd expect to receive it soon, and proceed.  

This procedure is almost impossible unless there's certain disclosure to a property.The bad thing, the good house is gone in 90 seconds.

I got lucky and just signed a 5 year lease with a 5 year option to renew with a dental practice!

What's the proper procedure here in Florida?

It trains the tenants to follow our procedures NOT theirs.So, you could have the few actual emergency calls handled by a trusted family member or friend and make it worth their while to do so:)

The property now cash flows nicely and I plan on repeating the same procedure with another home. 

Just make sure you still have robust screening procedures and policies in place.

Now that I moved to another State, and can't go to my properties on a moment's notice, I see how easy it is to eventually lose my gains on capex if my PM doesn't stick to procedures, can't/won't go themselves to see important issues as they arise, and after they are fixed.

It has nothing to do with whether they care or not, it has to do with their investor guidelines or internal policies and procedures for short sales.

The targeted area includes mostly undeveloped or under-developed land around our local small airport as well as some more retail/commercial/office areas in a nearby more densely developed commercial district that is a mix of run-down industrial-ish buildings (building materials, feed store, Goodwill), banks/groceries/fast food, services (dental, tax, etc), small older strip malls, a few empty/torn down lots, and some new and nicer retail and low rise office buildings, including a brand new grocery being built on a recently relocated Ford dealership site, etc.
