Wanting a vacation home!What is a good DTI ratio for a vacation home? We would be at 38% with the new home, but is that too high to qualify for a 2nd home mortgage? Also, if we only put down 20%, how would we know what the PMI would be, since that will likely increase our DTI?March 06 2012 - Avalon00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
