I have a W2 and other investment income, so it isn't like I am dependent on it, but just a cool milestone in the back of my mind.

I can give you much more specific info if you would like it via email or phone.

Even if you create a non-CA LLC, if you are managing the business from California, you will likely be deemed to be "doing business" in California and therefore likely subject to CA taxes.

Likely worth $250ish. - being all cash in it bothers me but isn’t end of the world I guess.

Are there concerns like location, zoning or land use, or is it simply about passing the inspection if it's a residential use?

The issue I faced was with the lender not with FlipSystem. sounds like someone got a nasty gram from FLIP system lawyers :) Can I do that mate?

For $75/year that seems like a good value but wanted to see people's experiences with actual members.Thanks!

Well, you can put your self on the federal opt out list here:   https://www.optoutprescreen.com/This might be great time to do it as if you have purchased any property within 23 or 24 you likely will be in the money to refi already or soon.

As an investor myself, I have seen areas like Cleveland and Dayton with COC ranging from 10-18%.

It sounds like you are doing everything right.
