@Lino B. that is an additional indictment of your managerial skills.Serve them with a notice to cease and quit.

So should each additional LLC have it's own Name?

That would be a very appropriate 1031 exchange scenario.If you go the 1031 route you will pay no tax and that tax will go forward as additional purchasing power for you. 

The difference in costs was close to an additional 600 per unit. 

However, if the $31k lien makes the house “under water” he could claim the inability to bring additional cash to close, going back to the “ability to deliver clear title” clause.I’m just going off Our standard realtor contracts.

in addition to the paid national searches most of us do.

My goal is to build up enough cash flow with adding additional rentals(15-20 rentals paid off) to one day being able to afford a vacation rental and renting that out until I’m at retirement age.

In addition you need to be able to provide the new tenant the keys so you have to somehow keep track of them because I doubt that they want to break into the house every time they want to enter.  

Additionally the subject property is a split foyer while all comps are bungalows.

We ripped off the "indoor jacuzzi room" and breakfast nook because they were horribly done additions that were already falling off the house.
