Quote from @Kathleen Park: I recommend you educate yourself on "ordinary wear-and-tear" vs damages, depreciation, and your state laws.Do yourself a favor: buy "Every Landlord's Legal Guide" by NOLO.

However, they told me that I have to rezone my property as commercial and that I have to comply with a bunch of different regulations like updated landscaping, parking, etc.

so if you just buy a random property with 100% financing, you'll never pay back the loans with the property - you'll be negative and  have to pay it back with other money.and if you BRRRR using 100% borrowed money you have to really knock it out of the park to get all your money back, which is very difficult to do as a new investor.the way BRRRR works (as you know) is you buy (with money - cash from your checking account, cash from your uncle, hard money, a HELOC, a cm) fix the property up, then refinance. 

Plus covered garage parking and all utilities included. 

RV parks ( we would be new to this area of investing ).

I saw there are lots of roof-mount implementations on parking lots/high schools in CA recently.

., outdoor areas, parking, kitchen facilities).

Maybe try some places or a broker that would insure an ATV park for liability with my logic being if they would insure that, they may insure anything lol

For example, at two events in the past week I met: a Dr. couple looking to get into investing, someone with four houses, someone with two duplexes, someone with a title company and 64 doors, someone with a couple apartment buildings and a winery, someone else with a title company and a parking lot striping company.

You’ll definitely want to dig into the zoning and permit requirements for your area to get a clear picture of what's allowed and what the associated costs might be.Also, don’t forget to factor in things like parking and whether you’d need to add a kitchenette to make it a viable short-term rental (STR).
