Can you get a bank loan on a property willed to you to pay for deceased funeral?

It will depend on the lending institution and if they would be willing to take a risk. Normally lending institutions insist that you hold title to any property you wish to borrow again. If the person is still alive that may leave you the property, then it would be unlikely that you would be able to secure borrowing against the property, as Wills can be changed at any time. Even after death a Will needs to be legally ratified.
