I feel one caveat (and complication) is that this person's lot will be exclusive to the rest of the park.  

This enables you to take advantage of 15+ years of experience and a team of experts, without any additional cost to you.SummaryI’ve worked almost exclusively with investors for over 15 years and selected hundreds of investment properties.

Does anyone have any MTR or STR properties exclusively renting to traveling professionals in the LA area?

I do not believe that increasing the value of homes and communities and providing secure affordable housing are mutually exclusive. 

Probably not enough to justify looking for the Sec121 exclusion, especially at ~$155k.Really depends on the rest of your financials. 

Yes, see Section 121 exclusion which lets you exclude $250,000 per person, $500,000 per couple. 

I'm a licensed agent and work exclusively with investment properties.

and instead of LLC I mean limited is just waaaaaaay more exclusive.

Obviously don't go in blind and with no game plan, but if your numbers/gameplan is realistic and achievable, sometimes its just getting your feet in the door is what matters most.That being said, cash flow and appreciation don't have to be mutually exclusive.  

The best thing is you don't have to choose one option in exclusivity to the other.
