What/with whom are my best chances of getting a small mortgage?

I have recently bought a house abroad that requires a certain amount of refurbishment in order to make it habitable/rentable. Due to the fact that it is envisaged that the amounts charged by local building contractors will increase dramatically in the not-too-distant future, I am anxious to get the refurbishment done a.s.a.p. (Otherwise I would have been tempted to wait until I had enough saved in order to do the work). I reckon that 20,000/25,000 Euro should be more than enough to do it. The property cost 55,000 but it is reckoned that refurbishment would probably double that value (although I have no intention of selling it, as it is not an investment property as such - this estimated increase in value would just be for the bank's benefit). The increase in value vis-a-vis the cost of refurbishment is largely due to the fact that it is envisaged that I will do much of the work myself, with the help of family/friends.

My problem is that I am currently acting as a full-time carer for an elderly parent and have a very limited income. However, I have virtually no outgoings on a weekly/monthly basis and I rarely get the time to go out, so what I receive as Carer's Allowance (200 Euro per week) is largely disposable and should be adequate to meet repayments on a mortgage of that amount. While the weekly income amount is not huge, it is steady & secure. Is there any financial institution that would regard me as a safe bet for a mortgage of that amount, on that level of income? Is it also going to be a problem that the property is situated abroad?

Any help or thoughts would be much appreciated.
