How does this work? I want to buy a new house and try to rent our current one. Is it hard to find renters? Is it hard being a landlord? Is it worth the aggravation?

Also, in terms of financing how do you get approved for a new home if you still own another house? Do they ask for proof that it is being rented and if so, what is the proof?

TIA!!!!

Oh yeah, and any realator/mortgage recs?
