Will my car finance or credit card be a problem?

They are counted as monthly commitments and reduce affordability a little, the same way the student loan does. Clearing a card just before you apply is sometimes worth doing and sometimes not. It depends on the size of the payment against your income.

The full answer

What actually decides it.

Not a problem, but not nothing either. Neither a car payment nor a credit card will stop you getting a mortgage. Both will reduce how much you can borrow.

The mechanism is straightforward. A lender works out what you have left each month once everything you are already committed to has been paid, and lends against that. A car payment of two hundred pounds a month is two hundred pounds that cannot go towards a mortgage, so it comes off before the borrowing figure is worked out. A credit card works the same way.

Outstanding balances are looked at as well as monthly payments, and this is the part worth asking about rather than guessing at, because how a lender treats a balance is not the same as how it treats the payment on it.

None of it is hidden from a lender, so there is nothing to be gained by leaving anything out. A lender runs a search before it gives you a decision in principle and a full credit check later, and both will find your commitments. What we do first is ask you for your own credit file, so that what goes on the application matches what the lender is about to see. A commitment that is declared and priced in is routine. The same commitment discovered halfway through is what costs people an offer.

Whether to clear something before applying is a genuine question with no general answer. Clearing a card reduces your monthly commitments, which helps. Clearing it with money that was going to be your deposit reduces your deposit, which usually hurts more. It depends on the size of the payment against your income and on how close the two figures already are, so ask before you move money.

Where lenders differ

  1. Every lender deducts your monthly commitments from what you can afford. That part is universal, and no lender overlooks it.
  2. Where they differ is in how an outstanding balance is weighed alongside the payment on it, and in how a card you clear in full each month is treated compared with one carrying a rolling balance.

Each one has its own page, because each one is a different problem. The whole set sits together on the foundation dentist hub.

And the one every stage asks: What does the advice cost

How it goes

  1. 01

    A conversation

    What you earn, how it actually arrives, and what you are trying to buy. No credit check at this point.

  2. 02

    The income case

    NHS contract, private work and dividends assembled into a picture an underwriter can accept, with the evidence attached.

  3. 03

    The lender search

    The panel searched on criteria as well as rate, so the application goes to a lender whose rules already fit you.

  4. 04

    Through to completion

    One adviser start to finish, with protection discussed alongside the mortgage rather than after it.
