A simple way to compare offers is to look at the Annual Percentage Rate (APR). The APR is the annual cost of a loan to a borrower and it includes other charges or fees. These charges and fees may include mortgage insurance, closing costs, points, and loan origination fees. When comparing mortgages, a higher APR indicates a larger upfront cost.
Lenders should always provide a document called a Loan Estimate when you apply for a mortgage. The "Comparisons" section of the Loan Estimate can help you determine which loan is the best fit for your personal circumstances. Not only does this section list the APR, but it also explains how much the loan will cost in the first 5 years. If you apply to multiple lenders, you can use the "Comparisons" section of Loan Estimates to compare offers between lenders.
