HelloFrom what I understand, with no experience in real estate investing, mobile homes only depreciate and that banks don’t see them as having any increase in value after repairs.

But I’m not sure what is better option, creating a website via a builder or a custom development?

Myself I have a building  background and possess journey level skill in almost all trades except maybe doing concrete work and I am also an architectural designer so I perfer properties that can be increased in value through forced appreciation and look for properties where the zoning, set back, and other requirements allow for adding square footage to a building but others perfer invest in turnkey properties already fully occupied whereas I like working with empty buildings. 

In my experience the inspectors were fairly "petty" when it came time for the Section 8 annual inspection / rental increases.

What percentage should I increase it by?

I might not have been clear...I did not have PMI in my case, I just meant to advocate that I would get rid of it ASAP, if possible, as it increases equity and cash flow if renting.
