Debt to Income (DTI)
This is the ratio that helps a lender understand the usage or breakdown of your income. For instance, if buyer A make 70,000 per year, is applying for a $1,500/m mortgage and only pays $500/m for a car, his DTI Ratio is ((500x12)+(1500x12))/70,000 = 28.6%. This is an ideal ratio. If buyer B makes $120,000 per year and is applying for the same mortgage but has $6,000 a month in reoccurring debt, his front‐end ratio is 75%. This DTI is too high according to current lender guidelines and would not qualify. Front End DTI is your mortgage divided by your income. Back End DTI is defined as the mortgage plus all of your monthly obligations divided by your income.
