I just checked - there aren’t any in my zip code. No surprise, my kids said a girl in his school drives a Lambourgini. I told him to see if she has a date for homecoming. HA!
Look for all the mortgages the US is buying up to go Section 8.
Often you won't know if there are. In many cases the property owners will not advertise them as such (eg on Craigslist) but will gladly rent them out to section-8ers since they are a reliable and timely source of rent. One way to tell is to visually look at the house. If it looks like it doesn't fit in with the rest of the neighborhood, and there's no mistake about it, it's likely section8.
