Now that everyone has chimed with their answer on some question that you didn't even ask, I'll try and answer the question that you did ask. A lender really doesn't care how many and how big your loans are. They look at your debt payments as a percentage of your income. The general rule of thumb is about 35 to 40 percent (Ideally about 36 percent, but some will stretch to 40 percent with a good FICO score). So in other words, they want your monthly payments not to exceed about 36 percent of your monthly income.
