I’m not big on sharing, so I’d eventually buy them all out and take full control of the property.

Many will cover water, pest control, repairs to the roof and exterior walls, fences, landscaping, maintenance, security, insurance, some cover cable and internet.

Unless you invest via an LLC owned by the IRA, you will not have checkbook control over the funds which means you need to run transactions (e.g. income, expenses, etc.) through the trust company who will need time to process the transactions and generally charge fees for each transaction.

I have 2 grandfathered rent controlled.

There would be no impact to other units.Now, I'm no electrician, but here's one way I could see a problem: 8 condos share 400 amps of service, but each has a panel with "100 amps."

I love having complete control and not having to deal with middleman scenarios.

Call pest control.

Is statewide rent-control on the horizon? 

Better control over labor.

I'm a newbie to REI with limited capitol, living in San Francisco in a rent controlled apartment, but that may be ending soon.
