I have rental income from my property in australia and I'm wondering if im able to and if so how to add in appreciation value into my foreign rental income on my self assessment ? Also if interest on my mortgage is allowed to be included into my self evaluation for my foreign income? I've read that interest isn't accepted on a UK rental property but in the foreign income section there's an option to add interest on a mortgage for rental property? As interest is deductible on my Australian tax return does that mean it's allowed for UK tax return?
