The old flooring is no longer available, so we are looking at either replacing the flooring in one bedroom with something that doesn't match perfectly , or redoing the flooring in the entire apartment (except the bathroom and kitchen; I already replaced the kitchen floor with a luxury vinyl plank and we have ceramic tile in the bathroom).I would love to get a point of view from other experienced landlords about the possible monthly rent difference and caliber of tenant difference if I had a totally uniform floor in all rooms vs having something different in that one bedroom.

I don't bother with incorporating in CA, just file out of state and get a cert of foreign status. 

But since you are incorporating the license into your investing plan, get it and find the right broker.
