As someone who's spent the past 20 years building software to ingest massive amounts of random data, the short answer is, it's really difficult to get accurate contact data.

Being in a mentor's group you're more likely to find someone willing to sign with you than you are from a random stranger on BP or at some networking event.

You can only play games for so long.Chances are your next door neighbor is an IRS agent and turns you in when your tenants blocks their drive or some other random event disturbing your IRS neighbor.ADU catches fire and your insurance won't cover you, because it was an illegal and unpermitted structure.The city inspector told the last guy not to build or rent it, and is now pissed and wants to make an example of you and just red tags the whole property and no one can occupy for the next 1-2-3 years while you wait for a hearing.Then when you get the hearing, "staff" recommends you tear the whole structure down, and if you still want an ADU, you can apply for a permit and rebuild it.Your tenant quits paying rent and won't move out and you can't evict them, because there is no valid lease and they're just your "roommate".Probably a dozen other bad things can happen to you when you do stuff like this.

Hi @Sean Leahy - good direction, I've never considered this but now that I think about, whenever I've had some random rental/sale listings I've been approached by brokers who said they represent folks that are part of the insurance company's claim management process (e.g. their house burnt down due to an accident). 

This is just some random Airbnb customer service person, so I wouldn't take this to court, but it seems fairly clear that what is being suggested is possible. 1.

When you do that groups of people will apply, rather than random individuals.

This lady saw my posts and randomly started attacking me (and others) with no credibility behind her arguments. 

Could you imagine having a bunch of STRs in Dallas and then the city randomly pulling the rug out from you?

if you buy a random property 3000 miles away and have to hire out everything and overpay for everything you won't.
