If your apartment-hunting style is more about number-crunching than ogling listing photos—or if it's a mix of both—you might want to take your search over to RealtyHop, the new sales-focused site from the team behind rental search database RentHop, that offers up classic listings, but with a twist.  

In addition to the usual details, RealtyHop serves up the estimated investment potential of each property in the form of a cap rate, to help you suss out an apartment's value like you would an investment.  (Quick review:  A cap rate is the annual operating profit--estimated rental income minus annual expenses and common charges--divided by the purchase price.)  They also provide a touch-of-a-button mortgage analysis alongside monthlies to help estimate your monthly nut.The cap rate analysis is most useful if you're hunting for condos—many co-ops don't allow or strictly limit sublets, so rental income is a moot point—but it's also an interesting way to look at your apartment's value, and weigh the costs of renting versus owning. 

The following listings—an Upper East Side two bedroom steps from Central Park, an Art Deco studio in Midtown West, a loft-like two bedroom in Downtown Brooklyn, to name a few— all fall within a cap rate range of three to five percent, which RealtyHop says makes them lucrative but reliable investments. If you’re in the market for an apartment that could generate some serious rental income one day (co-op buyers: be sure to inquire about the building's sublet policy), check these out.
