W-2’s allow mortgage lenders to identify exact income amounts and whom they belong to.
For example, if the homebuyer(s) have changed jobs and/or there are multiple borrowers applying for a mortgage loan together, then the w-2’s will allow the mortgage lender to assess how much was made at each job and by which applicant as the IRS Tax Returns alone do not provide this information as all w-2 income is lumped together as one line item.
