A one-bedroom apartment is always going to be more expensive than half of a two-bedroom apartment, which is always more expensive than 1/3 of a three-bedroom, and so on. \n\n<br><br>E.g. in a neighborhood where a 1-bed rents for, say, $1000, a comparable two-bed might go for $1500, while a three-bed might be $1800 and a four-bed $2000.
