We are closing on a home in Greenwood, IN in September and just found out the I-69 interstate expansion is scheduled to begin in a couple of years less than a mile west of our new home. From the plans, no homes in the neighborhood will be demolished and we will still have about 3-4 house rows between us and the highway. There will also be a on/off ramp just south of our home. I have three questions: Should bring up to my appraiser or should they already know? If they know, but the construction will not begin for a couple of years, will it have an impact on our appraisal now? Finally, does this typically lead to lower property values or higher values?
