Most married couples prefer to make joint mortgage applications rather than a sole name mortgage. Over the years house prices have risen quite significantly and with house price inflation outstripping wage increases over the years. In most cases, two salaries are required in order to qualify for a large enough mortgage.
However, sometimes situations occur where one salary is enough to justify the borrowing amount. There can also be additional reasons why one of the applicants doesn’t want to go on the application. This could be due to;
Possibly one applicant has a previous credit problem, maybe a bankruptcy or a CCJ which is preventing them getting a mortgage at the moment. If this is the case, providing the spouse or partner is not connected to that issue then the mortgage application could be made in their sole name.
This person would need to be careful to try and avoid creating a financial association with their partner if they want to guarantee that their own credit score would remain unaffected by that issue.
The maximum borrowing capacity as a couple is generally lower as rule, than if the working applicant took out the mortgage in their sole name. This may be due for example when one partner is currently not working.
Age of the applicants has a bearing on the mortgage calculation sometimes, if you have one applicant aged in their 50’s. For example, buying with a younger partner then it’s possible if the younger applicant is a good earner that they could borrow more as a sole applicant.
It may be that there are stamp duty or other tax implications which would lead to an applicant preferring to apply on their own.
Some Lenders are quite strict about married applicants having to do the mortgage in joint names. Most probably because they are concerned that this could in some way affect their security in the future. Especially if the couple were to divorce.
