How User Psychology Drives Rental Platform Design: Boosting Conversion with the “Hundred Billion Subsidy” Model

Background

As the rental business expands, a new commercial model called “Hundred Billion Subsidy” has emerged. Unlike e‑commerce, each rental listing is unique, so designers must find ways to increase conversion while respecting the scarcity of inventory.

User Psychology

Understanding six fundamental human motivations is essential for designing effective experiences:

1. Small Money, Big Deal

Renters seek the lowest price for the best property, wanting maximum benefit for minimal spend.

2. Trust Is Hard to Build

First‑time users are defensive; trust must be earned through transparent, reliable experiences.

3. Time Pressure

When users feel time is slipping away, they experience loss aversion and act quickly.

4. Greed

People are naturally drawn to greater gains, especially when incentives are clear.

5. Fear of Loss

Losing something feels more painful than gaining the same amount feels rewarding.

6. Fear of Being Scammed

Financial transactions trigger heightened concern about fraud.

Design Strategies Aligned with Human Motivations

Addressing “Small Money, Big Deal”

Show the coupon‑after price prominently on entry cards and property detail pages.

Highlight the value gap between original and discounted prices in red, emphasizing the extra benefits users receive.

Display annual discount information under the coupon price to amplify perceived savings for long‑term leases.

Use downward‑pointing arrows to reinforce the discount narrative.

Reinforce the coupon price and benefits on the payment page.

Addressing “Trust Is Hard to Build”

Present both the discounted and original prices side by side to make the discount transparent.

Show comparative statements like “cheaper than similar units in the same community” to prove the offer isn’t a price gimmick.

Addressing “Time Pressure”

Place a countdown timer above the subsidy card, using a distinct icon to draw attention to the limited‑time nature of the offer.

Addressing “Greed”

Emphasize the value gap on both static and floating purchase buttons, repeatedly reminding users of the high return on a small investment.

Highlight non‑price benefits in the coupon rights section to increase perceived value.

Addressing “Fear of Loss”

Add scarcity cues such as “only 1 coupon left” on entry cards.

Use action verbs like “Grab now” to create urgency.

Display a “limited to 1 per user” notice on the purchase button.

Addressing “Fear of Being Scammed”

Include official platform guarantees at the bottom of the property detail card.

Provide clear usage instructions on the coupon page, e.g., “Full refund if the property does not match the listing.”

Outcome

By aligning design decisions with these psychological drivers, the platform delivers maximum perceived value, reduces user defensiveness, and significantly lifts paid conversion rates.
