What the fourth bedroom costs
The answer block above compares the median asking price of four-plus-bedroom homes with the median of everything else listed in the city; the gap is what the extra room, and usually the extra square footage and lot, is priced at today. Compare on price per square foot, not price alone: a four-bedroom home at 2,000 square feet and one at 2,800 are different purchases, and the MLS square footage on each listing page makes that comparison in seconds. Newer subdivisions tend to deliver four bedrooms in less square footage than older ones; the community pages show year-built ranges so you can see which is which.
Questions to ask about any four-bedroom listing
Is the fourth bedroom a true bedroom with a closet and window, or a converted den, garage bay or bonus room? Are the bedrooms split (owner’s suite away from the others) or all on one side? Is there a second full bath near the secondary bedrooms? What does the seller pay for insurance and, in an HOA community, what do the dues cover? A local agent who works the area will know which builders’ four-bedroom plans hold their value.
