The current owners of #5K in the Devonshire House purchased the three-bedroom pad for $3,590,349 in 2011. Now, they've put it back on the market $5.4 million, a pretty hefty price increase considering a) how little time has passed, and b) how little they probably had to do in the way of renovations. The floorplan is exactly the same as it was when they bought the place and both the old and the new listings boast "modern interior finishes by Victoria Hagan." Really, the only change that seems to have occurred in the past two years is that Alec Baldwin moved into the building's top floor and began to assemble his Devonshire House empire. The chance to be Alec Baldwin's neighbor: worth a 50 percent return on investment? Guess we'll find out.
