For instance, at one home I saw a crack in the walkway by the steps leading to the front door.

Very tiny kitchenettes.

There's only so long one can hang onto unrealized losses when the cracks start to emerge.

The state is trying to crack down on unethical wholesaling

They pull any moisture they can get out of the air, so if there are any small cracks or openings to outside air they will just continue running, filling up their tank from the moisture in the outside air and not working efficiently at drying out the space you’re trying to dry very well.

They might tell you that there is something wrong with the place, or the neighbor's place across the street is a crack house so they don't want to live there, or......

Here in TX the soil is mostly clay, and it shrinks and expands with humidity level (thus the need to "water the foundations" as a measure to avoid foundation cracking), so foundation problems are a common occurrence.

What are the Best Practices in Planning a Tiny Homes Community?

How would I advertise the spaceI was also considering buying a few tiny homes and placing them on the empty portions of the lot.

It just has weeds that grow through the concrete cracks.
