I am a Real Estate investor in Colorado looking at doing something similar, I put together a syndication here to work on a development, starting next year to build tiny home neighborhoods in the local area.

If you're just starting, I'd suggest you attend some local meetups and network with some local, established, successful investors.  

I am with Vlad on this: Call the local HA directly.

TN offer OTC, it's extremely benefit to locals that knows the area well.

It is advertised as having a platform that you can pull lists of note holders in any area plus a cheap skip trace feature. 

When it comes to buying windows for your house flip, you might want to consider checking out local home improvement stores or even online retailers for a wide selection.

The heat pump system was installed by a small local contractor. 

How many Adults (of local, legal, age...18, 20, 21) ?

Check local laws to see what you can do.
