My state says I'm required to give "reasonable notice" before entering the property.

Very few good property managers want to deal with the low income areas for the same reason owners don't.

This would be the only reason I would go after one. 

I think you're jumping the gun for two reasons.1.

In the meantime, I had a bad experience with a local (Seattle area) custom cabinet maker so I'd love some recommendations on folks who do high quality work, but are reasonably priced and responsive.

If so, another reason to use a RE atty because of different state laws.

Does that seem reasonable ? 

There’s a reason the government specifically calls out “ rent to own “ in the Dodd frank bill a “ predatory lending practice” Save yourself a huge headache and move along with someone else

Lots of people that own and operate house flipping business opt to structure either an S Corp or LLC taxed as an S Corp, but you have considerations like drawing a "reasonable salary", self-employment tax, etc. 

You have not needed a LLC for 5 years and there is no reason to think you need one now.
