It really comes down to the real human condition of certain communities and instead of brushing it off, walking away, to actually be involved in them. 

@Zachary Beach hey Zach, how’s the insurance costs up in the brush area?

That's just math  Can I brush it?

People need somewhere to put their make-up, brushes, razors, etc. 

Brush up on the code changes in your part of CA - If you find a property with a large main house + a second kitchen (ADU or MIL) that could be a lot of rental income on your first purchase. 2. 

Look, that plumber was not into getting into things and he gave you and tenant the brush off, that's the reality of it. 

If you were to lose signicant money on a deal and you can't just brush it off.. then you need to pay for title commitment. 

Brush up on building code requirements: in basements you're looking for egress windows that are 5.7 sq feet or more openable (3ft by 3ft casement style windows work best), and ceiling heights 6ft 8 inches or greater (as little as 6 ft 4 inches is ok under ductwork and beams though)2.

Get a strong shop vac with bristle brush and carefully clean off the condensing unit. 

However, my point from the beginning was that I can paint with that same wide brush and say most (not all) realtors are just as worthless.
