Worked as an emergency room RN for a few years, then went to work as a fleet diesel mechanic, and now run operations for buried telephone repair across the St.

I guess he thought about it more after the fact (and got upset) as when I came to the property today, he posted a Mechanic's Lien for the amount he said he was not charging me for.

In order for a subcontractor or supplier to file a mechanics lien on your property in FL......they must have sent you a proper Notice To Owner form within 45 days of First performing any work on your property And must File the actual lien within 90 days of completion of their work. 

In NC,technically, anything structural, mechanical (HVAC), plumbing or electrical other than the simplest of things.

You will need to service your tenants when they report a problem, units need to be turned, mechanicals need to be serviced etc.

One went right through the siding and into the mechanical closet, another one right through the master bedroom window!

Mechanicals will go out, eventually. 

That's true.Has anyone had luck arguing that technically both partners have a controlling interest or found any other mechanism to be able to transfer title into the LLC?  

Call it a different mechanism for taxes all you want, it's going to hit your bank account when you need to fix it. 

Suffice to say, the analogy is doing a paint job on a unique car - but leaving the mechanicals in place without addressing reliability.
