Hi
We are just in the process of sorting mortgages etc.
It seems as long as you can provide proof of income, ie employment contract and payslip in our case, there does not seem to be a problem.
Our bank have been very helpful (BNZ) and although to begin with we are asking for a larger mortgage until the house sells in the UK (still only 80%)they seem quite happy to help us out. A word of warning is that they still want to see what is coming into and out of your account. I made a spreadsheet on the computer listing our full incomings, outgoings, Erics salary per month and what our intended monthly bills would be ie mortgage repayment, household bills, vehicle expenses, shopping etc. So it may be worth having something prepared in advance just in case and for your own piece of mind. Also bear in mind that they may want to see bank statements from the UK for 3 months and also details of pension funds, life insurance, ISA's, savings etc. Best to be prepared than be caught out.
Hope this helps. Amanda
