I am NOT in the business...but, just went through financing for a mortgage and did MUCH shopping around!! This is what I found:
Pretty much everyone SAID 28/36....but, they also mentioned that each one had their own "in-house preference"...it seemed to be 36/40 in my area...most said the front-end doesn't matter to them...they wanted to keep the back-end at, or under 40.
We were approved at 3 local banks and our numbers were 36/44, so, go figure??!! We were told because we have a 71% LTV and decent reserves they were able to let us go higher in the ratios.
So, you can see there are a lot of variables that really make up what a lender wants to see as far as ratios go. I think if you can get through AU or LP...most banks will try to work with you. AU & LP have been know to approve loans with up to 70+ back-ends, from what one lender told me!?!?! That is craziness, which is probably what led to the mtg. crisis?!
I would check with a local lender, it seems everything is changing on a daily basis!
LP is Loan Prospector used through Freddie Mac...AU is Automated Underwriting used through Fannie Mae...this is what lenders have told me......if I am wrong, others will let you know!
