About this home

Very well maintained 6 family in a great location generating very consistent rental income today with the potential for substantial rental increases without any capital improvements required. This 6 family has all 4 room, 2 bed and 1 bath units with 5 of the 6 units currently rented to subsidized tenants. New owner will benefit from the long time current owner empowering his property manager to maintain this property the right way. With off street parking and well laid out units this property currently generates over ten thousand five hundred dollars a month. However, recent HUD increases in Mattapan have paved the way for this property to see a jump of close to two thousand dollars a month simply by increasing the current subsidized tenants up to the new payment standard. Allows a buyer to pursue this property being offered at the current market value and see a significant increases in value shortly after purchase simply via paperwork and nothing else.
