If the tenant "abandons" the unit based upon facts (no notice in writing, but all non-trash personal property removed, utility changed billing, , etc.), I advise writing a "Notice of Abandonment" letter to the tenant that is mailed and emailed to last known address. 

The more complex to construct or non-standard finishes = more money. 

I think this is your public expert in FL.... http://buyingtaxdeeds.com/  The national road shows in my opinion are not really helpful.  

More often than not, the property situation is public information but it hasn't yet been listed.

If you need any connections to contractors, insurance agents, title companies, appraisers, deals (off-market single families, duplexes, fully renovated turnkey properties, multifamily properties, buy and hold deals etc I have several deals that come across my desk each day), recourse and/or non-recourse lenders, my opinion on potential properties you are analyzing to buy etc I am more than happy to help you. 

My attorney advised that I could put up a non-refundable option fee for maybe $100 - $500 dollars for a period of time that goes by and then increase for each # of days that goes by in the contract, so for instance:(Option Fee - not Earnest Money)$500 give to seller 3 days after contract is signed.If close hasn't happened within 15 days, give them another $500.If close hasn't happened within another 15 days, give them another $500. 

The house is about 1400 sqft and is close to public transportation.

Here is the IRS publication regarding residential rental property which also defines when the asset is considered "placed in service" and with examples too. 

(I know it's public record, but this may add more information to your situation.)If you are self-managing now, how did you not know they were clearing the snow?

You also need to make sure the LLC has not previously been funded with non-retirement funds.
