Hi Carlos! Thank you for the comment. I would highly recommend that you speak to an experienced lender because I don't believe that's a hard and fast rule. In my experience, some borrowers have been able to get up near 50% of their debt to income ratio (FHA allows for POSSIBLY 57%, though I believe the mortgage percentage maxes out at 47%). In order for you to get accurate and specific information, feel free to email me and I'll send over some great and trusted lender names. You can simply have a chat without feeling forced to commit. They'll be able to help determine your specific max purchase price.
