In my city the worst schools and lowest value neighborhoods are directly tied to mobile home parks.

Granted the market I bought in is much cheaper than yours, but I could've bought a house of the same size, same distance from campus but a different direction, but older and with less upgrades inside for about $60,000.

Quite a bit of your direction will be determined by valuation and timing.  

Any recommendations or directions are appreciated!  

Lots of people have the discussion about tax and legal implications, which there are many and should be discussed with an accountant and attorney, but you'd want the LLC if you want to buy properties directly in the name of the business without having to do quit claim deeds and run the risk of having the loan called due.

If you do get a permit, your code officer will guide you in the right direction and inspect your work. 

As was mentioned earlier, they do direct deposit and the money shows up in my account like clockwork.

You can check out some of my BP blog articles here that are based on my South Lake VR for some insights and also feel free to reach out directly with any questions you might have regarding nuances to purchasing in Tahoe.  

Ideally I'd prefer refi w/cash out but I'm hoping to use the HELOC to get started in that direction.

Because of this, I will either be able to roll over my pension for discounted stock options in the new company or roll over into a self directed IRA or cash out with penalties.
