For LA, I think you want to get the max bedrooms that you can given the space because the rents are going to be pretty juicy if done right.

I was at a live tax deed auction once and the last property up for bid was a dilapidated 70s era mobile home on a leased space in MH park. 

Cubicles, bad bosses, TPS reports (Office Space reference) are all great motivating factors. 

IDEALLY, we would like to find a property that has or is capable of being converted into a “mother in law”, “ADU”, “Casita”, or any other separate living quarters in which we could rent out the main portion to a tenant (short term or long term) and then use the separate space as our own for when we come and go with business.

Space X is growing there and Elon has plans of this city.

I've wondered about some sort of artists'/musicians' retreat space, but not sure about the numbers of that.I would love to hear your ideas!

That ends up leaving a void that's filled by unprofessional, and in some cases outright criminal operations there in the PM space.

Instead they are "flex spaces" or "offices".2.

Someone has a gas stove and the new rental only has electricity; someone has a 33 in fridge and only a 30 in fridge fits; counter space is cut for slide in, not drop in; etc.

I agree we are quite active in the space.
