The short answer
DoorLoop's pricing page lists Starter at $69 per month billed yearly or $99 billed monthly, Pro at $149 or $189, and Premium at $209 or $239, with the price rising as you add units and an onboarding fee based on portfolio size. Tenants who pay rent by ACH are charged $2.49 per payment on Starter and $0.99 on Pro. Photo inspections are a paid add on on every plan.
Letting charges $59 per month for up to 25 units and $189 for up to 150, with inspections included and no onboarding fee. It does not collect rent online: tenants keep paying by bank transfer and Letting matches your bank export to each ledger. If you want rent collection, screening and listings inside one app, DoorLoop does that and Letting does not.
