This townhouse property is perfect for an owner occupant wanting plenty of space and quality finishes within a multifamily property. Unit #1 (currently vacant and digitally staged in photography) has three bedrooms with two full baths with natural stained doors and trim. The other two homes are smaller. One is a two bedroom townhouse, the other is a one bedroom "walk in" apartment. The combination of sizes make it perfect for extended family. Suffolk Street has seen significant investment in recent years. Check it out! Many of the homes have been newly built or renovated, and are getting premium rents because of its convenient waterfront location. This property was previously three condominiums. The buyer may be able recreate the association with the document package that was used previously. This potential option provides added value upon eventual resale. See an attorney and the multiple documents attached.
