Unused finance costs on Foreign Property where do I enter in the tax return

hi
Where in the tax return do I enter the unused finance cost on a foreign property, to be carried forward to next years return?
Or is it that the unused Mortgage interest cannot be carried forward on a foreign proerty?
Confusing as I can see box:
Unused residential property finance costs brought forward:
(optional) Which would be if there was some finance carried forwrd from last year, but where do I enter this years unused finance costs for next year?
Many thanks in advance.

Hi wood1e
There is no box for you to enter the unused financial costs.
You will need to keep a record of these and enter them in box 45 of your return for the following year to use these against any future profit.
Please see guidance at:
Work out your rental income when you let property and the notes for BOX 45 on the Self Assessment: UK property (SA105)
Thank you

ok many thanks for that comfirmation Could you also confirm the value that I enter for 'Finance' is it the full amount even though that is more than allowed?
or do I enter the allowable amount? 
ok 
and BOX45 is NOT for Foreign Property ?

Hi,
Please enter the total amount, this will be used to calculate the basic rate reduction to your income tax.
If you are referring to box 45 on the SA105, page UKP2, then no, this is for UK property income.
The equivalent for foreign property income is on SA106, page F5 box 24.2.
I include the link to the SA106 guidance- Foreign notes
Thank you.
