Generally, the maximum period of leave that lenders can consider is 12 months. However, they view smaller periods such as 6 months or 18 weeks more favourably.
We have a lender on our panel who can consider your application if you’re returning to work within 2 years of parental leave.
If you’re clearly going to struggle to afford the loan while on leave, the bank won’t approve your application. All lenders we deal with practice responsible lending.
