As I am interviewing brokerages, with the goal of being investor focused, what questions should I be asking?

@Paul Harris a few episodes ago on BP Frank Rolfe was interviewed and provided a ton of valuable information.

If my employee quits and I no longer will use her services, should I recognize income equal to her future unpaid salary because I'm now relieved from having to pay her?

I would interview the local commercial agents in your area first. 

You could interview GCs and do a design build process as well.Financing can be done through local and regional commercial banks.

If your monthly payment is $500, and your closing costs are $5,000 then you would need to recognize $6500 (5,000 +(500*3)) with your bank sometime before closing.The nice thing is you could borrow money from parents or what have you then recognize the amount, then give it back if you're strapped for cash.

Don’t throw away all your dad hard work get a property manager negotiate his fees make sure you read over the contract and interview more than one.

This is how investors get a bad rep within the real estate agencies.However, if you interview several agents and let them know you're looking to work with someone exclusively for your investment portfolio, you can vet each agent to find one that works well with you. 

( I don't recognize the acronym, sorry)

This will frame up your questions when you interview with different shops.
