...one thought about never, or infrequently driving past your properties, if you don't tend your garden, you'll get weeds, and weeds left unchecked, will overgrow your flowers...

I can't imagine maintenance on brand new tiny homes would cost much, especially if you did composting toilets and rerouted any grey water to a garden or something you'd have no plumbing to worry about. 

I currently live in a senior and multigenerational community, original owners from 1980s, we have garden day once a month.

Some great neighborhoods that have great schools, and low crime in the Orlando area are College Park, Winter Park, Windermere, Winter Garden, Maitland, Baldwin Park, SoDo (south downtown), Dr Philips, and Oviedo. 

I've recently been offered 2BR mezzanine, garden and penthouse opportunities there through RETA. 

@Tim West Yes - exactly my vision would be a different feel - community gardens, laundry facility, perhaps a guest suite that they could rent for overnight guests.

I have plans for land I want to purchase to build self-sustaining animal sanctuaries with vet services, growing food for them.Also more land to build self-sustaining low income/homeless developments, with career assistance, training, garden including growing vegetables to get them on their feet and possibly into home ownership when they move on if they wish it and they can also pay it forward.

If that became a problem, maybe I'd offset it by buying a cow or growing a garden. 

Because it will all be one lease, they can pay their own utilities and with drought tolerant landscaping there can be no gardener.

Maybe try knitting or gardening?
