@Bryan HartlenManaging low-end properties can be demanding due to higher tenant turnover, increased maintenance needs, and frequent rent collection issues.

Professionals find good deals, operates them professionally hopefully providing a profit without you have to deaL with the issues that face a landlord every day. 

Note that Sec8 comes with added costs & issues due to bureaucracy and state of the HUD departments in the area.

None of these communities will be changing to residential neighborhoods, although a couple do have residential 'sides' that full time residents live in and can not be rented short term.Two of the big communities that you will have some issues with self managing are Reunion and Margaritaville.

The buyers did a long inspection, multiple days... made a huge request for concessions based on what we knew to be purely made-up issues.

I think the engineering issues on them have been resolved.I've used a number of different brands (lower price point) and haven't had issues with any of them.

Quote from @Jim Stanley: You should reserve insurance for large claims.Contact the city and report the issue to them.

There are a lot of site-specific issues you need to investigate before deciding what the land is worth to you.

A weak team leads to guest complaints, maintenance issues, and poor reviews.

Since you can’t do a formal inspection, a detailed contractor walk-through and phased renovation estimate are key.Have you considered checking city records for past permits to uncover any unaddressed issues?
