Home-Buying and Mortgage Decisions As their apartment rent increased each year, Zoe and Luis Martinez started thinking about buying a home. For a slightly higher amount each month, they could become homeowners. However, their student loan debt might be a barrier to obtaining a mortgage.

This financing choice would probably require mortgage insurance and could result in financial difficulties if housing prices decline. They must also consider closing costs and the real estate agent commission. Zoe and Luis also discussed whether to use an online mortgage company or a local one.
