My plans was to develop the 90 lots in two phases and sell the lots to a tract builder.

In fact bought large tracts of land in Mohave County Arizona just across Hoover dam from Las Vegas. 

Every 40-acre tract of land was sold in about 18 months - all using seller financing provided by my father.My father had all the property sold and producing a cash flow Before the first payment was due to the poker player.This is an excellent example of how to invest in real estate without the burden of debt.It is also an excellent example of knowing the details before negotiation begins.My father’s situation is also an excellent example of being extremely good at what you do.

Nashville, for example, limits (to an extremely strict degree) the number of Airbnb permits they'll give out (per census tract) to investor-owned properties.This limit has seemed to keep people from bothering to get permits, thus skipping out on taxes anyways. 

Pretty much all of Chicago falls into a "no income limit" census tract, so most often these days 5% down on a 2-4unit primary residence is an option!

I can't vouch for markets other than Cleveland, but here things can change very drastically on a street by street basis and just looking at census tract statistics won't give you enough information to understand that. 

I bought a typical, stucco box, tract house here in California back in 2009.

Other than the pending legislation changes, one other thing to consider is that the city currently limits the number of STRs to 3% of properties in any particular census tract.

Hell, there is this burgeoning website, census.gov, which provides essentially any element of demographic data one could ever imagine down to census tract block groups (which, in cities, is a very small, concentrated area). 

The home matched the quality of the non-tract homes of my neighborhood.
