"When I saw the tenant's deposit in Whale and off my books it was a good feeling. Like relieving me of a burden. I was a little concerned about the process and making the change, but it was so easy and that feeling of relief makes it feel like Whale should be a no brainer for landlords." *

"Whale is solving a real problem in multifamily. Whale’s platform streamlines the entire process, eliminates administrative headaches, and unlocks real value for our teams and our residents.

The genuine 'win-win' scenario for residents, who can actually earn interest on their deposits, and operators, who save time, money and mitigate legal risk, shows that Whale has created something special. Whale is setting a new standard in how deposits should work.” *

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.
