7. What should a purchaser do if a mortgage is needed?

It is best to inquire at a bank(s) about the possibility of a mortgage on the flat in question before you sign the provisional sale and purchase agreement.  Failing that, the purchaser should apply to a bank for a mortgage immediately after signing the provisional agreement.

What if the purchaser wants to acquire an additional and/or second mortgage?

The purchaser needs to check whether the first mortgage allows an additional and/or second mortgage before applying to a bank for an additional or second mortgage.
