I thought I could solve the vagrant problem by buying and repairing the buildings.

That aside, If it were me I'd get a professional estimate of what repairs would cost, and make the decision to keep or sell based on that. 

I've had a lot of large repairs in the past year that just kill the cash flow.

Renting out mobile homes can be a great source of cash flow but they’re notorious for being damaged significantly by tenants and tend to need a good bit of repairs before renting out to the next tenant.

Though my property management company eventually took care of the eviction proceedings and repaired the property to prepare for a new tenant, I feel they were negligent in their duties.

I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

to BRRRR something, you need a goldilocks property - something distressed enough that it can be bought substantially below market, but not so distressed that it can't be repaired. 

Quote from @Alecia Loveless: @Natalia Perlova Absolutly no to the Sunday repair.

Zoning says that it is a repair service shop, excluding automobiles, any idea if leasing out storage space would be permitted?

Here are the airbnb links if that helps get a better idea of what I'm trying to describe.airbnb.com/h/treehouseyurtairbnb.com/h/yurtundertheliveoaksI had an investor ask me at what price point I would consider selling, that's what prompted me to dig a little deeper into determining what it is actually worth to a prospective buyer.
