Look into a local REI or Landlord Association and network with the local investors as well as hanging out here.

Do you go to local real estate meetups? 

What do the local codes say about a rebuild for an existing non-conforming parcel with a greater than 50% loss?

I would take in all you can on this site, also the books you read and getting to see people speak/network at the local REIs.

@Anthony Ervin, typically these inputs are a combination of market research, talking with local industry professionals, and some of your own instincts.  

The best thing all of us can do is meet with our local apartment associations and as a group reach out to local lawmakers to enact improved, landlord-friendly squatter laws on a local level.

Post it in all the local FB , and BP groups 

Try a local community bank or credit union.

Developing connections with local real estate agents might also help you receive replies more quickly.Connect with local professionals by going to networking events and meetups for real estate in the region.

@Mark Walker I would call every local bank in your area too.
