The short answer obviously being "Jesus, no, there are way more useful things to do with that amount of money, if you're lucky enough to have it." But, that being said, it sort of is? If you stack it up next to this converted stable renting out in Cobble Hill for $25,000 a month?
This one at least can at least boast some legitimately cool (and valuable?) historic bona fides: architect William Tubby built the place (located at 405 Clinton Ave) in 1889 for Brooklyn's then-mayor Charles A. Schieren, and in spite of a recent renovations people are calling "splendid beyond belief," the owners have hung onto the original 19th century bathtub.
There's also a pretty spectacular backyard, assorted fancy kitchen appliances, a "fitness center," six actual fireplaces, and an in-house library with floor-to-ceiling shelves and one of those cool rolling ladders you never actually see in peoples' homes. So! If not a "good deal," per se, we can at least call this place "totally deserving of our imaginary money." Or maybe your real money? I don't know.
