Could I get a mortgage for �18,000 to buy a property in bulgaria?

I would like to buy a cheap property in bulgaria for around �18,000,but I'm not sure if I could get it.It would be a joint mortgage,but the only problem is my boyfriend has really bad credit,but my credit is good, and we are on family tax credit so our anuall income would be around �18000.We also already have a mortgage on our house which is �93000,our ages are 24 and 25 years old,If anyone could give me some info and tell me if I have a chance of getting one,that would be great.
