Fannie Mae and Freddie Mac have both extended the option to skip the traditional appraisal process in lieu of automated appraisals to purchase loans. Several months ago, the GSEs announced they would offer appraisal waivers on some refinance loans to borrowers who have at least 20 percent equity in their homes. But last week, Freddie said a traditional appraisal also would not be necessary on every purchase loan. The changes take place Sept. 1. A few days later Fannie announced appraisal -free mortgages on some purchase loan applications. Both GSEs emphasize that the appraisal waivers are only permitted when there’s enough data on the property.
