Congratulations on thinking ahead. A professional Realtor would definitely want to meet with you and help you prioritize any projects to help sell your home and preserve your equity. Since this is often the start of a business relationship, there would be no charge.
The listing is a vacant lot, and does not yet have a street address. It is Lot 39, Mountain Road, Deerfield, NH. Zillow has it listed twice under the same MLS number - once as 39 Mountain Rd, which is wrong, that is the street address of another place on Mountain Rd, and once as 39 Baker Ave, which is 8 miles from the vacant lot that is for sale!
