Check out local areas and homes, meet with pros, and look into financing like regular loans or FHA loans.

Depending on location you may also need regular pest control and pool services. 

This way you share your location and identity in every post.Network locally at investor groups.

I also recommend using as many regular, vanilla mortgages as possible before going over to DSCR mortgages.
