How to Get a Mortgage with Variable Income or Bonuses
If your pay changes month to month or includes bonuses, commission, or overtime, securing a mortgage can feel complicated. Many lenders only consider basic salary, while others can include a proportion of your variable income. Understanding how this works is key to maximising the loan you can access.
How Lenders Assess Variable Income
Lenders treat variable income differently. Most will average bonuses, commission, or overtime over 1–2 years to determine what counts towards affordability. Some, however, only accept a percentage, which can reduce your assessed borrowing power.
What matters most
Regularity: Consistent bonuses or overtime are more likely to be fully counted.
Evidence: Payslips, P60s, and employer statements help demonstrate your income.
Recency: Lenders prefer recent income trends to reflect your current earning potential.
Common Challenges for Variable Income Borrowers
Applicants often encounter obstacles such as:
Bonus or commission not fully counted by some lenders
Large variations in income year-to-year
Rejections for overtime-heavy or commission-heavy pay structures
Difficulty predicting affordability due to fluctuating income
These challenges highlight why generic online calculators rarely give an accurate picture for variable income borrowers.
Step-by-Step: Maximising Borrowing Power
1. Gather Your Documentation
Collect recent payslips, P60s, and any employer letters detailing bonuses or commissions. Complete and accurate documentation strengthens your case.
2. Understand How Each Income Type Is Treated
Different lenders value overtime, commission, and bonuses differently. Knowing which income counts most helps identify suitable lenders.
3. Choose the Most Favourable Lender
Some lenders accept a higher percentage of your variable income. Selecting these lenders can significantly increase the amount you’re able to borrow.
4. Secure an Agreement in Principle (AIP)
An AIP confirms your potential borrowing amount and allows you to make offers with confidence.
5. Submit Your Full Application
Provide all relevant payslips, P60s, and supporting documentation. Clear records help lenders assess your variable income accurately and speed up the process.
