rental income from renting rooms in own home on mortgage?

[Michael M.]

I own a multifamily home.  I live in one unit and rent out the other.  

In the unit that I live in, I rent out the other rooms.  

When I apply for a refi or a mortgage for a second home, can I include this rental income in my application on top of the rental income that i receive from my rental unit (I have 2 years proof of income from the room rental on income tax returns).  I was told by a chase mortgage guy that rental income from renting rooms in my own apartment won't count.  Is this a rule, or does it vary by lender?

Thanks!
