Designing a Home Loan That Balances Borrower Affordability With Lender Profit
Company: LendingClub
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a new kind of home mortgage that borrowers can afford and that still earns a profit for the lender offering it. Explain who the product is for, how it works, why it is easier to afford than the loans available today, and how the lender earns a return and manages the risk it takes on.
```hint Find the cost you can remove
Break down what a buyer pays to get into a home with a mortgage, both up front and every month, and look for a piece your design can shrink without simply moving the same cost or risk back onto the lender.

### Clarifying Questions
- Does "affordable" mean a smaller down payment, a lower monthly payment, a lower total cost over the life of the loan, or easier qualification?
- Which borrowers is the product meant for: first-time buyers, owners who are moving or refinancing, or anyone?
- Which market and rules apply, and does the lender keep the loans on its own balance sheet or sell them to investors?
- How soon must the product be profitable, and what return does the lender need on the capital it commits?
### What a Strong Answer Covers
- A definition of affordability and a chosen borrower segment, with the reason for the choice
- The mechanics of the product: what changes in the down payment, rate, payment schedule or ownership structure, and how the borrower eventually exits it
- The lender's economics: where revenue comes from, who bears credit and house-price risk, and a rough check that the numbers work for both sides
- Regulatory and consumer-protection constraints, including lessons from past mortgage products that looked affordable but harmed borrowers
- A launch plan with a primary metric, guardrails and the main risks
### Follow-up Questions
- How would the product hold up, for borrowers and for the lender, if home prices in your launch markets fell sharply?
- How would you explain the product's full cost to a borrower so they can compare it fairly with a standard mortgage?
- What evidence after launch would make you redesign or withdraw the product?
Overview: A product design prompt asking candidates to create a new kind of home mortgage that borrowers can afford and that still makes money for the lender. It tests how they define affordability, choose a borrower segment, structure pricing and risk, and plan a compliant launch with clear success metrics.
