Definition
The rate at which available homes or units are sold or let in a given market over a specific period, usually expressed as units per month. Lenders and valuers use absorption rate to stress-test a developer's sales programme and assess whether projected sell-through timelines are realistic. A typical new-build scheme in a strong South East market might show an absorption rate of 2–4 units per month, whereas weaker regional markets may sustain only 1–2.
