Obviously if I held all these properties long term I could continue to 1031 from property to property and indefinitely defer long term capital gains.

Obviously, the two questions that need to be answered are 1- Is the OP designing a solution for which there is no problem?

Obviously, cash flow would have to be such that you could absorb a salary, but it seems it might be better to have someone trained by the owner who is present for everyone in the building as necessary.Thank you all for your thoughts!

Brown, I obviously don't use other registered agents so @Nathan Gesner suggestion is pretty good. 

The bank valuation should obviously be a useful objective view on the valuation of the property.

That's because the city won't calculate the actual amount till a structure is built, aka it's not just a plot of land anymore.This will obvious cause your property tax bill to go up and also your mortgage escrow account as well (sometimes these things can make your mortgage shoot up a few hundred a month). 

Obviously the HOA is keeping values in this neighborhood down because an owner would have a mortgage plus another $715/mo for the HOA, which only covers use to a community center but nothing else.Besides holding costs, is there anything else I should be concerned with for a flip on a land lease? 

Very tough market for cash flow obviously and remote investing has never been easier

Quote from @Jeffrey Mair: Hello, I am seeking advice or creative ideas to move closer to the goal of owning a home in San Diego county without the obvious solution of selling off my small rental portfolio.

Every market in residential zoning has an expiration date, we just don't know what it is yet.The obvious solution is to buy in already regulated areas with tourist/commercial zoning.The returns are lower, but at least they can't go to zero overnight.
