Jumbo loans allow you to borrow more money than conventional loans. They also come with stricter qualification standards and different tax implications. To get a jumbo mortgage, you'll need more proof of income. That means two years' worth of tax returns and other documents. Jumbo lenders also prefer borrowers who can prove that they have enough liquid assets to cover at least six months of mortgage payments. There is little chance of you securing one of these loans with a credit score lower than 720. Typically, you can qualify for a conventional loan with a "fair" credit score of 620 or higher. Also, conventional loans require you to have a debt-to-income (DTI) ratio lower than 43% in order to qualify. Jumbo loans don't have a set debt-to-income ratio requirement, but most lenders will want to see a significantly lower DTI.
