Taking out a loan after Mortgage Completion

Myself & my partner have recently completed our purchase on a property which has been lived in by an older person and needs a considerable amount of updating.


We need to take a loan out to cover the costs of the renovation, however having researched into this a lot of people are saying this could be an issue with our names not being on the electoral roll.


We aren't actually living in the property at the moment so our home addresses are the ones assigned to our credit reports as we both lived with our parents rent free, but when it comes to applying for a loan they will ask us questions such as do you own a house and is it mortgaged etc...this is where I wonder, are we allowed to apply for the loan at our parents home addresses where our electoral roll is registered, but also state we own a property and pay a mortgage?


I am in the process of adding us to the electoral roll for the new property but would preferably like to get the loan out soon. I do have back up funds in the meanwhile which I can use from other savings but if the above option is available then I will apply that way.


Thanks
