Hi, I am the trustee of a property of my parents in NC.

If have parents to co-sign that can work!

Moving out: During the beginning of the pandemic, young renters left the big city to hole up with their parents.

Their parents are very involved and they love our safe location and renovated units.Because they are outside they love and take advantage of our parks, beaches, town and public transportation...Never an issue with rent (but that has been the case with all of my tenants), and they absorb increases in stride.

We'll need to figure that out very soon.Either way, I want to split my portion so that I have 100% control going forward.Is the best way to do this, to separate the 19 condos into his and mine?

Could you hire a property manager to control these headache-properties?

Most custodians that allow for checkbook control do not set up the LLC.

I would love to own all my real estate 100% with full control. 

It's not money for nothing (and your chix) for free.You will have to spend time working at it.You should ask yourself--is doing the things I need to do to operate this rental business, and taking the financial risks I need to take the right thing for me.Also do you know enough (in your judgement) to be able to start in on this yet.For instance, do you know what a P-Trap is, what about bug control, do you know how to legally evict someone in your town, and do you have money set aside to do this and also to "Turn" the unit for the next customer/renter while still paying the mortgage?

Capex is wildly variable, but I'd go with at least 3.5%, playing off the 27.5-year depreciation rate for residential properties...but that's only AFTER the initial period, over a very, very long period, if you are tightly controlling costs. 10% is more reasonable, and some years, especially early on with delayed maintenance, it'll probably be 100%+.
