Utilizing Roommate Rental Income

[Tony Le Claire]

Good evening fellow BP'ers, Here I am at 12:08 AM searching the depths and nether regions of Google and BP hoping to find some information on a question I've had for quite some time. I've tried searching various key words and phrases and can't seem to find what I'm looking for. I'm under contract for a SFD primary residence here in Phoenix, AZ. Found it on the MLS, had everything I wanted/needed in my first home purchase, etc. I'm considering renting out one of the rooms. My plan is to establish a lease agreement similar to how I would if I owned a multi unit property. I would screen the tenants, etc. Furthermore, I would make sure to report the rental income on my taxes for at least two years. The rental income would likely be $400-500 gross per month realistically for a furnished room. Fast forward a couple years, I'm now looking to move into a new primary residence and retain the this first property as a rental and would rent out the whole residence. When I go to apply for the new primary residence mortgage, would renting out the room for a couple years and reporting the earnings on my taxes qualify me as a "landlord"? Meaning, could I now consider the projected rental income for the whole property as a factor in my loan application? Or would I only be able to have the $400-500 that I was actually earning for the one room considered? Thank you for your time and consideration! -Tony
