One option I haven't noticed being mentioned is to auction it.

I wouldn't build the ADU just yet because like it was mentioned it cost more than you can really make a good return on.

It's also really cold outside as well, which he mentioned that "we don't want anyone dying of exposure". 

The things you have mentioned are simple, high level thoughts based on assumptions.

Thanks for mentioning the KIND of job that someone like me wanting to be more involved in real estate could look for.

When one looker was questioned, she mentioned she was the owner of the house across the street and wondered why there's a big, long line.

If so, as @Brandon Weis mentioned, they come in all "shapes & sizes".You'll get more assistance if you post an example here and ask more specific questions about it:)

I agree with Erik, although their are some investors out there that will help fund the down payment/entry fees that you mention, they typically are friends and family that trust you and believe in you.

Keep in mind that BP Pro members will get 15% off the subscription price and $100 in in-app wallet credits for paid plans, as Jenell mentioned.

Now that you mentioned this, I looked into it and, at a glance, they offer "Full-Service Maintenance Coordination", which offers the phone answering, troubleshooting, etc.
