High-stoop, detailed brownstone, with coveted curb appeal, shakes up the Central Harlem house market with price tag that calls condos to mind, instead of spacious, 4-story, 3-family, lovingly renovated townhouses. With leafy trees embellishing the well-maintained facade & front garden, plus your own, quiet backyard oasis, purchasers of this 11-room home might opt to keep the lower duplex as their own 3-BR space--while drawing income from the modern, 1 BR floor-thru apartments now found on the 3rd & 4th floors of 2050 Madison Avenue. The new owner of this brownstone might use funds left over from this "below-market price tag" to transform this 1920's-built property into a one-family stunner, yielding 4 expansive floors to live graciously well on. The current duplex offers a flowing eat-in-kit, with granite counters & breakfast bar, tons of oak cabinetry, full-size appliances & designer lighting. The front parlor living room has high ceilings & 2 windows looking out on this lovely Madison Avenue block. Sunlight reflects nicely off the hardwood floors here, as well as in the rear bedroom (that some might use instead as a formal dining room). Shower in bath is set off by glass brick, ceramic tiling, marble floor & attractive vanity sink. The garden level of this duplex provides 2 roomy bedrooms, with big, tiled bath in middle, including spa tub & laundry area as well. Rear garden is fenced in for privacy & has both masonry grilling, patio area along with your secret garden for exercising your green-thumb skills. Cellar @ 2050 Madison is clean, concrete floored, & claims terrific ceiling height. Great mechanicals, gas heat, separate hot water heater, 220 electricity. The two upper-floor apartments here have kits with tiled backsplashes & workable layouts + fine appliances for the urban chef. Bright, cheery vibes fill these rental units' commodious front living areas, & bedrooms are at the rear of this brownstone. No-lease 4th-floor apartment is a tad larger than the one below. Indeed, this townhouse still has another 1,404 square feet of air rights that might be built on by the wise purchaser here. 3rd floor, month-to-month tenancy, now supplying a market rent of $1995. Duplex is currently vacant: its market rent could bring in about $4700-$5000 a month. A wee-bit of TLC will make this townhouse shine. Snatch "2050" up before other thrifty-minded buyers in NYC beat you to the finish. Trains, buses, & Citibikes are at your beck & call here. Gourmet, greengrocer, supermarket, & boutique shopping to be found everywhere; health & fitness services abound; plenty of green space to explore; & restaurants like Red Rooster, Corner Social, & Harlem Tavern are mainstays for outdoor/indoor dining & takeout/delivery.
