Tuesday Real Estate Porn

As is my want, I was perusing the Sunday New York Times real estate section when I saw that a brownstone in my neighborhood is up for sale for $1.9M dollars. I'm always particularly interested in what brownstones go for in my nabe, since my grandmother owned one across the street from the house that was featured in The Royal Tennebaums. Seriously, if we had held on to that house, it would have been so sweet.

According to the Prudential Elliman web-site:

"MOTIVATED SELLER: Located in the gold coast of the landmark of Hamilton Heights' historic district, this thoroughly renovated 18.5'+/- wide, 4100+/- bldg sqft, legal 3 family brownstone boasts an Arts & Craft style three-bedroom / two-bath garden & parlor duplex, and two 2-bedroom floor-through units. Each apartment is equipped with a working gas fireplace(s), new stainless appliances, a granite counter top, and original refinished hardwood floors. Each is pre-wired for cable/DTV, and telephone; moreover, each is individually metered for gas & electric, as well as for heat & hot water. Large deck in the rear plus a garden. "

There is an open house on Sunday and I might just have to mosy on down to see it. According to the listing, the house could be turned into coops which means that the owner could sell the two other units and just keep the duplex (which would be what I would do). Seriously, you sell the two bedrooms for like $450,000 each and that's like half of what you would pay for the house.
Of course, I have no idea how this co-op thing actually works in terms of brownstones.

Question: Why am I talking like I can actually afford to buy this house?
