Lots of debate over buying vs. renting....
The OP could buy a legal two family, something with a legal accessory apartment or a property with mother/daughter potential (note: the residents do not necessarily have to be mother and daughter, that's just the term that kinda stuck on this type of setup). OP can also use projected rental income to bolster overall income for mortgage qualifying purposes, availing more areas and properties to consider.
Now... OP becomes BOTH a buyer AND a renter, but is the LANDLORD COLLECTING the rent....
Talk about having your cake and eating it too! And it will solve all this debating.
