Humans have a non trusting and skeptical nature.

I am not accusing you, but it's happened in the past multiple times here on Bigger Pockets in posts like these.Could you explain further about the many hidden problems of the house and the nature in which you addressed all the issues?

Single familyPros - available at every price point - easy to understand - comps are relatively easy to determine - numerous exit strategies available - less complex to rehab- less complex to BRRRR- better likelihood of natural appreciation - Less turnover - Fewer tenant headaches- Tenants pick up most/all of property expenses (also, no common areas)- Tenant more involved in upkeep- More financing optionsCons - a lot of competition (regular buyers, other investors)- inherently slower to scale than multi familyMulti familyPros- scale up is built in - more cash flow vs amount invested?

They take pride in the community and if you care for them properly you will find them naturally policing the park like an owner.

If you have slop behind it, that's from where most of the water is coming into your backyard - that wall should "capture" it and redirect it on the sides, and eventually, further out along the sides of your house following the natural ground slope (see pictures below).The backyard seems flat - one way or another you'll have to find a way to slope it and move water along.Just my 2¢.

With the unpredictable nature of timeshare assessment fees and maintenance fees, I would probably avoid that deal.
