What a comparable unit would rent for in today's market.
Market rent is the rent a property would command if leased today, based on comparable rental rates in the same submarket. Market rent is determined by rent comps — recent leases of similar units in similar properties — and is the benchmark against which a property's in-place rents are measured.
Market rent is the rental analog of comp sales — it answers what a unit would rent for if listed today. The data sources are similar: rent rolls of comparable buildings (from CoStar, RealPage, or property manager networks), asking rents on competing properties, and recent closed lease signings. The most reliable input is recent closings — what tenants actually agreed to pay — not what landlords are asking.
The difference between in-place rents (from the rent roll) and market rents (from current comps) is called loss to lease. In-place 10% below market means 10% rent growth opportunity as leases roll. In-place 5% above market means stretched tenants and likely move-outs at renewal. Both directions matter — loss-to-lease creates upside; in-place-above-market is a risk signal.
Market rents differ sharply by submarket and unit type. A 1-bedroom in Chicago's River North might rent for $2,400; the same 1-bedroom in suburban Schaumburg rents for $1,500; in South Shore, $850. Even within a single building, unit position, view, floor, finish, and renovation tier produce 10–30% rent differences. Detailed market rent analysis goes unit-by-unit, not building-level.
For investors, market rent matters at three points. Acquisition: identify in-place vs market gap to validate value-add upside. Operations: re-lease at market on every turnover. Disposition: support the pro forma rent assumptions used in the sale marketing. Underestimating market rent is a chronic problem — many owners default to "what I've always rented for" rather than refreshing analysis annually.

Pull recent lease signings from CoStar / RealPage if available, comp asking rents on Zillow / Apartments.com, and ideally survey property managers in the submarket for closing rents on similar units.
Asking rent is what landlords list units for. Market rent is what tenants actually agree to pay. Market rent (from closed leases) is the more reliable number; asking rents reflect landlord hopes and often include concession adjustments.
It's the benchmark for in-place rents (loss-to-lease analysis), the basis for pro forma rent assumptions on value-add deals, and the floor for renewal pricing.
At every acquisition / disposition, and at least annually on holds. Markets move quickly — rents that were $1,400 two years ago might be $1,650 today, or vice versa.
