How to Get a Mortgage with Variable Income and Sales Bonuses: A Case Study

Summary

When expectant parents Adam and Sarah faced tight deadlines and complex, variable incomes, traditional high-street lenders struggled to see the full picture. First Select leveraged specialist underwriting to package Adam’s monthly sales bonuses alongside Sarah’s flexible school hours, securing their ideal family home ahead of their baby’s arrival.

For first-time buyers, purchasing a home is a major milestone—add an impending birth to the timeline, and the clock starts ticking twice as fast.

When Adam and Sarah discovered they were expecting their first child, their priority immediately shifted to securing a permanent family home. They found the ideal property, but they faced a strict deadline: completion needed to happen well before Sarah’s due date. Moving house is like managing a flight schedule—timing is everything, and unexpected delays can throw the entire plan off course.

* Clients:           Adam & Sarah (First-Time Buyers)
* Timeline Demand:   Fast completion needed (Pregnancy)
* Primary Income:    Sales Base + Monthly Variable Bonus
* Secondary Income:  Part-Time Variable Hours (Education)
* Challenge:         High-Street Income Shading
* Solution:          100% Bonus Retention Specialist Lender

The Obstacle

When Adam and Sarah initially approached high-street banks, they encountered immediate friction regarding their income structure.

  • Adam’s Bonus Reliance: Adam worked in high-performing sales. While his track record was consistent, a significant portion of his total earnings came from monthly performance bonuses. Standard high-street algorithms typically “shade” or cap variable bonus income, taking into account as little as 50%—or ignoring recent upward trends entirely.
  • Sarah’s Variable Hours: Sarah worked part-time at a local school. Her monthly take-home pay varied depending on term times and additional support hours worked each month. Lenders often struggle with non-standard hourly patterns, defaulting to the lowest monthly average rather than actual earning potential.

To an automated lending algorithm, Adam and Sarah appeared as high-risk, lower-affordability applicants. In reality, their combined household income was robust, reliable, and more than sufficient to cover the mortgage repayments.

The Engineering

Navigating complex lending parameters requires looking beyond rigid automated scoring systems. Think of a mortgage broker as an air traffic controller directing a flight through adverse weather: when the direct path is blocked, you plot a precise, specialist route to reach the destination safely.

First Select stepped in to restructure the presentation of their financials:

  1. Holistic Income Packaging: Instead of relying on standard automated uploads, we compiled a granular breakdown of Adam’s sales commission over a 12-to-24-month horizon. We demonstrated that his “variable” bonus was, in effect, a regular, dependable baseline.
  2. Specialist Lender Selection: We bypassed lenders with rigid algorithmic caps and placed the application with a specialist lender whose underwriting criteria allowed for 100% inclusion of regular sales bonuses.
  3. Optimising Part-Time Hours: We contextualised Sarah’s employment by presenting a weighted average of her academic year earnings rather than treating low-hour months in isolation.

The Outcome & Takeaway

By matching Adam and Sarah with a lender who evaluates real-world earning capacity rather than relying on automated assumptions, we achieved full mortgage approval on optimal terms, giving the couple the financial clarity and confidence they needed.

  • Approval: Full mortgage offer issued in time to complete comfortably before the birth of their baby.
  • Affordability: 100% of bonus income accepted, securing the exact loan amount required without requiring a larger deposit.

Key Takeaway: Variable income does not equate to un affordability. If your earnings include bonuses, commission, or flexible hours, the key to success lies in choosing a lender whose underwriting reflects how modern professionals are actually paid.
