It may only be a matter of time before strict short-term rental regulations in Texas cities, such as Austin, are a thing of the past (or at least significantly limited).

This would be your detached garage / in-law suite type use.

Statute of limitations can be somewhere in the 4 year range based on contract law. 

The property consists of a SFR plus a "in-law cottage". 

In California if you do 8 or more wholesales a year you need a licensee by law

Some HOA's are more strict then others and depends on their posistion.

I'm not familiar with OH laws, but you'd want to work with the county or city zoning commission to discuss the process for re-zoning.

Apparently the laws on this changed in 2009?

Which makes me wonder why here in Los Angeles there is an extreme housing shortage, rents are going through the roof, the state recently passed an law making Accessory Dwelling Units easier to build in an effort to mitigate the the housing shortage, property values are at a level at or above the housing bubble peak.
