Those are similar to the guidelines I have for my property manager here in Columbus OH.

It's obviously a gamble when you deal directly with the listing agent as they are "making best attempt" to share their fiduciary duties.

What are the guidelines?

My suggestion there regardless of being within county guidelines or not is to keep your neighbors happy and don't give the city ANY excuse to look at your property.

There are no guidelines and terms can be  what they need to be.

Do they follow regular rent regulation/stabilization guidelines?

Yes, I realize this is a gamble with crappy odds. 

I became really passionate about multifamily investment and I am hoping to find a good deal in a 8-24 units apartment complex for our next investment.Many people talk about the key things to look for when selecting a market, like population growth, job growth, rental price growth, etc, but is there a website that combine these trends and that you use as a guideline when making your decisions?

I know the IRS guidelines require a competent person with an engineering or appraising background.
