The full answer
What actually decides it.
Not generally, provided the application goes to the right lender. Working across two or three practices is normal for an associate, and nothing about it makes your income less real.
What a lender needs is to understand it clearly: how many days you work at each practice, and what kind of work you do at each. A typical pattern is three days at one practice doing NHS and private work, and two at another doing mostly private. That leaves you with two remuneration statements, payments from two practices on your bank statements, NHS pensionable earnings relating to only part of your work, and tax information covering the whole of your self-employed position.
To a generic underwriting process that can look complicated. To somebody familiar with dentists it is fairly ordinary. The job is to build the whole picture from all of it, rather than reading your income off any one document in isolation.
That is the broker’s role here: to communicate how your income is made up and package it for a lender that will take all of it into account.
Where lenders differ
- The right lender takes all of the income into account, across every practice.
- The wrong one may take only some of it – typically whatever it can tie to a single document – and reduce what you can borrow accordingly. The income is the same in both cases; the difference is how much of it gets counted.
