What is the best way to explain this to tenants and enforce?   

For example, they may say the bathroom is fine but they don't want to see a separate kitchen there (I've had that happen in basements).As far as the extra electric meter, the simplest thing would just be to explain to the now-townhouse unit tenant that it used to be two units, so there are two electric meters/bills and they'll just have to pay both of them.

Read the lease, I'd imagine lock outs are explained in the lease agreement. 

Read your contract closely and ask your PM to explain anything you don't understand.

I hope that better explains my viewpoint.Good luck.

Explain to him you're the new owner, run through the new lease (make sure you have one made up) and discuss rent payment and due date.

Can you please explain the investor capital aspect alittle further?

I spoke to my realtor and she explained the process to me.

Are CPAs typically also tax advisors I could spend a few hours with them explaining our current situation, investment strategies and goals or do I need to find a tax advisor and a CPA separately?   

It's a civil matter, meaning adults need to figure out their personal drama and let cops focus on more important things.I would attempt to visit with all three occupants and explain to the daughter that she is not an authorized Tenant and that her parents want her out.
