I would worry more about the ACTUAL cost like insurance, water bill and fixing post purchase.Looking for investor now to get myself another building during this bad time.  

Actually taking the time to dive into, and learn real estate in a way that is scalable is like drinking from a fire hose, and theirs plenty of water!

Here are key sustainable trends in real estate:Green Buildings: Properties designed with energy efficiency, water conservation, and environmentally friendly materials in mind are becoming increasingly popular.

I am looking at a beach front home in gulf shores 6bed/6.5bath (No Pool).  

We have up to 50k in replacement revenue for downtime.If you have a pool, you want that specialty coverage of course.

All bids are to be based on the bidder’s own information and knowledge of the property, learned through his or her own efforts, and not on any representation or comments made by the Committee.The property is being sold free and clear of the lien(s) being foreclosed, and of all interests subsequent in right to that lien.The property is being sold subject to:All taxes due the municipality not foreclosed by this action,Water and sewer use charges not foreclosed by this action,All building and zoning regulations of the municipality which affect this property,All building lines, easements, restrictions and all other matters concerning this property which appear of record,The rights of any person in possession or occupancy of the property who have not been made parties to this foreclosure action,The right of the United States of America to redeem the property, if applicable under Federal law,Any other liens on this property which have not been foreclosed by this action.Further description of the property and further terms of the sale may be obtained from the Committee or from the court file.

They pretty much do exactly what you are looking for.This or you can get involved in a "pooled" investment (not my favorite option) but depending on the deal this might work as well

The easement must be evidenced by written instrument recorded in the office of the clerk of the circuit court in the county where such land is located before the recording of such tax deed or master’s deed, or, if not recorded, an easement for a public service purpose must be evidenced by wires, poles, or other visible occupation, an easement for drainage must be evidenced by a waterway, water bed, or other visible occupation, and an easement for the purpose of ingress and egress must be evidenced by a road or other visible occupation to be entitled to the benefit of this section; however, this shall apply only to tax deeds issued after the effective date of this act.197.573 Survival of restrictions and covenants after tax sale.—(1) When a deed or other recorded instrument in the chain of title contains restrictions and covenants running with the land, as hereinafter defined and limited, the restrictions and covenants shall survive and be enforceable after the issuance of a tax deed or master’s deed, or a clerk’s certificate of title upon foreclosure of a tax deed, tax certificate, or tax lien, to the same extent that it would be enforceable against a voluntary grantee of the owner of the title immediately before the delivery of the tax deed, master’s deed, or clerk’s certificate of title.

Finding maintenance issues prior to them becoming a larger problem (water leaks, pipes, roof etc.).

It reminds me of Bruce Lee's quote, "Be Like Water."
