The short answer
A rental comp is a current listing for a home genuinely similar to yours: same bedroom count, similar size and condition, nearby, and listed recently. Collect five to ten good ones, look at the typical rent rather than the cheapest, and send your landlord the two or three that best match your unit.
What rental comps are
“Comps” is short for comparables: homes similar enough to yours that their rents tell you something about what yours is worth. Real estate agents use them to price homes for sale. Renters can use them the same way, to judge whether a renewal offer is in line with what the same kind of home costs nearby today.
They matter in a renewal because they turn a feeling (“this seems like a lot”) into evidence a landlord can check. A request that says “three similar one-bedrooms on this block are listed at $1,850 to $1,900” is much harder to dismiss than a request that the rent be lower.
What makes a good comparable
Roughly in order of importance:
- Same bedroom count. A one-bedroom is not evidence about a two-bedroom, however close the price looks.
- Close by. Same building is best, then the same block or neighborhood. Rents can change a lot across a few streets.
- Similar size and type. Apartment against apartment, similar square footage.
- Recent. Listed now or within the last few weeks. Old listings describe an old market.
- Similar condition and amenities. Renovated units, in-unit laundry and parking all move the price.
Why a nearby unit is not automatically comparable
Distance is the easiest thing to check and the easiest to over-trust. Two homes on the same street can rent for very different amounts. A landlord will notice the difference even if the listing does not spell it out:
- Building quality. A new building with an elevator, gym and package room is a different product from an older walk-up next door.
- Condition. A freshly renovated kitchen or new flooring moves the rent, in either direction against yours.
- Layout and floor. A top-floor corner unit with light and views is not the same as a garden-level unit, even at the same size.
- What is included. Parking, storage, utilities or in-unit laundry may be in one rent and charged separately in another.
When a listing differs from your home in one of these ways, either leave it out or say how it differs. Acknowledging a difference makes the rest of your evidence more credible.
Where to find them
- Major rental listing websites, filtered to your bedroom count and area.
- Your own building's leasing website, which may show current pricing for available units, sometimes including yours.
- Nearby buildings run by the same management company.
- Signs and listings for homes on your street.
Save a screenshot or link with the date, address, unit size and asking rent for each. Listings disappear once they rent.
How many you need
Enough to see a pattern: usually five to ten strong ones. Fewer than three makes it hard to tell whether a listing is typical. More than ten usually means some are loose matches that weaken the set. If you cannot find at least a handful of close matches, the market evidence may be too thin to support a lower number.
Read the typical rent, not the lowest
Sort your comps by rent and look at the middle of the list. A landlord will dismiss the single cheapest listing as an outlier. A counter anchored near the typical comparable, or the lower part of a tight cluster, is much harder to argue with.
Account for move-in specials
Many listings advertise concessions such as a free month. The monthly figure overstates what new tenants actually pay. Work out the effective rent: a $2,000 listing with one month free on a 12-month lease works out to about $1,833 per month ($2,000 × 11 ÷ 12).
Presenting comps to your landlord
Pick the two or three closest matches and list them plainly. Let the evidence do the work; there is no need to argue each one.
Mistakes that undermine your case
- Including units with a different bedroom count.
- Using listings from a noticeably cheaper neighborhood.
- Relying on listings that are months old.
- Ignoring obvious differences, like a renovated unit versus yours.
- Sending a long list that includes weak matches.
Once you know the typical comparable rent, use it to set your counter.
How CounterRent helps
CounterRent pulls listings and rent estimates near your address, ranks them by building, bedroom count, size, type, distance and recency, and excludes the ones that would not hold up. It also tells you when there are too few strong comparables to support a counter. The methodology explains the approach.
