4. Understand how lenders make decisions

Mortgage lenders take the information on your application form and in your credit report and allocate a value to each item. The total is your credit score, also known as your credit rating. Generally, the higher it is, the easier you'll find it to borrow money.

But it isn't quite as simple as that. Every lender uses a slightly different calculation and some have different calculations for different mortgages. So you could have a different credit rating for every application.

The one constant in this process is your credit report, so make it as good as it can be.

5. Clear up misunderstandings

Make sure that your credit report is up to date and accurately reflects your circumstances. If you find anything you think is wrong, contact the lender that submitted the disputed information and explain why you disagree, you'll need to provide proof.

If you're right, they'll amend your report. And if something needs further explanation, for example, you once missed some repayments because of illness, you may be able to get a note added to your credit report that lenders will see when they search it.

Try to avoid so-called credit repair companies, they cannot help to change your credit history.

6. Register to vote

As a precaution against fraud, lenders use the electoral roll to check that you live where you say you do and are who you say you are.

If you aren't registered at your current address, they may ask for further proof of identity or even reject your application. You can download a voter registration form at www.aboutmyvote.co.uk.

7. Find the mortgage you need

You can do a lot of work on this before you actually submit an application by asking potential lenders for detailed information.

Just be certain that they do not think you're actually applying, or they'll make application searches of your credit report. Application searches leave a record, known as a footprint, which will be seen by your chosen lender when you eventually apply.

They can cause major problems and affect your credit score, the lender may think you have been rejected repeatedly, believe you're desperate for money or even suspect a fraud. If necessary, insist that they only make a quotation search, which will not be seen by other lenders in future.

8. Check your credit report again

It's important to check your credit report again before you put in your application. That way, you can ensure that all your good work is reflected in it, spot any mistakes and double-check all your details one last time.

Then you're finally ready to fill out the application form.
