Can be seen anytime with your Realtor: #1 is vacant. This owner built townhouse property is perfect for an owner occupant wanting plenty of space and quality finishes within a multifamily property. Unit #1 (digitally staged in photography) has two bedrooms, a finished lower level, two full baths, and natural stained doors and trim. The 2nd apartment home is a two bedroom townhouse, the 3rd is a one bedroom "walk in" apartment at grade. (not a basement unit!) The combination of unit sizes make it perfect for extended family or for additional income. Suffolk Street has seen significant investment in recent years. Many of the homes have been newly built or renovated, and are getting premium rents up to $3,200 because of its convenient waterfront location. This property was previously three condominiums. The buyer may want to 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.
