I ask them to ensure the apartment is in tip top showable condition, pay for advertising and pay rent until a suitable tenant that is properly vetted can be found, just as they were.

Are the mechanical system in stable condition?

There is a lot of asbestos siding in Florida and it poses no danger/health concern unless it is "bothered." 

So, I decided to ask a question as a BiggerPockets member.All I’m looking for is someone that I can feed analyzed “deals” or leads to for free in exchange for being able to walk the property while it’s in rehabbed condition and under contract (taking a cue from J Scott’s The Book On Flipping Houses).If the above paragraph doesn’t seem doable, then could I ask: “How can I help someone?”

If you don't have any photos or a condition report when they moved in, you won't have much of a case when/if it goes to court. 

The upside looks great, great rent increases and the asset looks to be in good condition, keep your cash, you may find another deal.

Zoning, outdoor storage is fairly rare, depending where you are, condition of the improvements, are you looking for just a metal building or some office too?

Not knowing these items will put you in a great position to FAIL.Once you have a decent handle on your market conditions and rehab number calculations (there are plenty of threads here that I and others have gone into full detail on how to do), then you can comfortably start looking for private money lenders.

If you keep the property from health and safety violations, manage like a business, and carry good insurance you are best off vesting in a single entity Revocable Living Trust- this gives you stand alone one property protection and saves a boat load of money.

You could physically tour the property to get an understanding of its complete condition and determine approximate rehab costs.
