Description

Live and invest in prime Park Slope with this ideally located handsome Brownstone containing a thoroughly renovated owners lower triplex and a high income upper duplex rental. The lower triplex is a 2304 SF 3 bedroom with 2-1/2 baths and includes a fully integrated lower recreation/den /office area. There is a magnificent south facing landscaped garden. The architecturally designed triplex was completely renovated in the last 2 years and features an attractive pallet of materials throughout that both preserves the significant character of this classic townhouse while providing a more contemporary lifestyle approach to townhouse living. All mechancical systems, including central A/C have been completely updated and/or are new. The faade, entryway and foyer have also been completely renovated providing both great curb appeal and thoughtful access to the upper duplex. The high income rental apartment also received significant updates when the lower triplex was built. The apartment is an attractive 1620 SF 3 bedroom with two home offices that retains a significant amount of its original details. The lower floor is all living with an open floorplan and a home office. The bedrooms and an additional home office are on the top level. The projected annual rent roll for both apartments is $186,000. The access to all that Park Slope is well known for is nothing short of superb.
