Yes, it is common to transfer title to your llc.  

The calculations for cost of replacing a tenant in each unit each year makes sense and I suppose is a conservative line to take. 

As this is a risk for me to tie up a chance of not selling to anyone for possibly 3 years, is it possible to "tie it up" for them, but say something like "price to be determined by appraisal at end of lease, with a minimum of $215,000" is this legal, or common?

@Jeff Ronningen it makes so much sense what you said.

It's a very common problem for people when they are getting started- build equity and/or save and you'll be fine.

Manufactured homes are commonly called "HUD Code homes" because the building code is federal in standard and is performance based, while Modular homes are built to state building codes.With both Modular and Manufactured homes, there are varying standard of quality.

But the land is  common area even though there is a fence marking 2 distinct yards.

Flipping houses and owning rentals are only similar in the sense that the underlying asset is property -- beyond that, they are completely different strategies that fulfill completely different investment needs.Every investment strategy requires you put in some combination of the following:- Time- Cash/Credit- ExpertiseAnd every investment strategy generates some combination of the following:- Profits- Cash Flow- Tax BenefitsWithout knowing what you have to put in and what you're looking to get out, there is no way anyone can recommend a particular path.

For the most part, it won't make sense to spend anything over 300k in this area, and deals are a little tougher to find right now. 

For example, a standard residential policy will provide $100-300k liability coverage while a commercial policy commonly provides $500k-1mil liability.
