It's not your garden-variety IRA.

I also really enjoy the process of taking something old or rundown, and making it new again, I just love seeing the results even if it's just a fresh coat of paint.

Whereas people in rural communities are often there for the space/acreage/freedom/gardening.

...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. 

Fix anything thats broke , give it a fresh coat of paint and rent it out . 

As an agent I always tell this to my investor clients who are looking to sell:If it is a single family home - you are better off selling it vacant with fresh paintIf it is a duplex/triplex/quad - leaving one unit vacant and "rent-ready" can be beneficial. 

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. 

Start fresh with new numbers and requirements.
