About this home

Public Remarks: Great opportunity. The owners are currently using the whole house as single family but could easily be converted back to a two unit, zoned for and doors there. Still has two electric meters. They purchased the home with plans to remodel, rented the upstairs for a few years, started the project and due to health issues could not do it. Now offered for a low price taking into account all the work that is needed. The roof was done in 2008 and a lot of insulation was added. Large yard and driveway. Upstairs electric heat and on separate meter. Seller would like to close at the end of June with occupancy 7/5. Being sold as is. Entered in MLS as multi-family home also.
