The local jurisdiction will have setback limitations that you need to follow and it will depend on the size of the mobile home.

My biggest advice would be pick the strategy, align your goals, take action despite any setback and you will be at 10 units in under your set 5 year mark. 

There are lots of restrictions like setbacks, height, lot coverage, parking requirements, access, ingress, egress, etc.

Anyone can be sued for anything in America, and being in compliance with all regulatory and contractual obligations does not guarantee a successful defense.

So, an RE sale would allow the borrower out if needed.In addition, most HAMP borrowers had temporary (I guess we are to believe) income setbacks as a result of the crash.  

I'm looking for my first opportunity (I just got my RE license last week) to get into investing so its good to see that if you get through the setbacks you can learn a ton and be successful!

It would be nice is while Trump is working on his regulatory hack and slash, he targets some of these financial rules/ . 

4) What are the size and setback requirements in your zoning district?

Not only by being hands on and by learning through micro-failures and setbacks, but also by opening yourself up to expanding your network. 

I'n hoping against hope that there will be changes made in CA leadership to bring some more middle of the road policies back, and get out of the race to always be the most regulatory stringent state, as they're just adding more costs to housing.
