These are referred to as Retrospective or Prospective appraisals

Yes, we can and do often. Retrospective real estate appraisals are quite common with our Attorney and Accountant clients. We can do a retro appraisal with a date as far back as our data will allow. Why would anyone need to know the value of real estate in the past? For many reasons! Examples include appraisals as of the date of death of a relative for estate purposes, or in the instance of a divorce, it could be the date that one spouse discontinued financial support for the mortgage payment. We can appraise a property as of the day before a fire caused major damage or a flood ravaged the property. As I stated above, the reasons are as varied as our clients.
