Obviously the HOA is keeping values in this neighborhood down because an owner would have a mortgage plus another $715/mo for the HOA, which only covers use to a community center but nothing else.Besides holding costs, is there anything else I should be concerned with for a flip on a land lease? 

@Carl Rowles Mobile homes are a niche of REI just like anything else.

I have a sibling who is looking to sell two single-family rental properties but is concerned about the tax implications.

Does anybody have any contacts for companies that will remove a dilapidated mobile home in the Jacksonville area?  

Both of these are legitimate concerns.

@Andrew Slezak I recommend you first articulate precisely the liability events or concern which are pushing you to transfer the property to an LLC.

I am concerned that your investment outlook isin't patient enough.

You must have helpful Section 8 agencies - anytime I've talked to the tenant's caseworker about issues they just say "not my concern".

So, I don't think frozen pipes were a concern.
