OUR METHOD

How it works

1. Whale requests security deposit
Once a renter’s lease is approved, Whale immediately requests their deposit.
2. Whale locks and confirms deposit
The deposit is held in cash and can only be unlocked by the landlord at lease end.
3. Renter earns interest
The renter earns up to 3.25% (APY) interest, paid monthly.
4. Renter moves out, charges deducted
Landlord completes their move-out process and Whale transfers the amount owed to the landlord’s bank.
5. Deposit is unlocked
The balance after any move-out charges is unlocked immediately for withdrawal.
