According to this site https://www.area-codes.com/city/city.asp?

Or you may be referring to local incentives (usually state or city based grants = free money) for communities that need people to buy primary residence in order to stabilize the town.

City websites and websites such as https://www.niche.com/places-to-live/search/safest...Do you happen to have any rule of thumb ?

@Jason Ma  All of San Antonio City is inside Bexar County. 

@Donna Welschmeyer Waco is an interesting city.

I would look up the city's development site and see where new development or public dollars are going.Once you get that info, find about 10 neighborhoods, go out and drive them and reduce the number down to about 2-4.

Alerts for "Kissimmee" or any other city you want would be great.

However prices vary from state to state and even city to city, so I would get a few bids. 

The $60-70k rehab estimate seems high as I'm shopping for an Inglewood condo and some of the worst 2bed 2baths in the city wouldn't require over $20k in repairs/upgrades. 

It is all interesting to me because I recently saw a similar type of program for backyard homes in Portland (company is called Dweller) where they lease the backyard and build a small rental unit in the back (homeowner gets a monthly check, buyout clause is there, 25 year lease).
