Looks like if you’re happy to do modular flying with Aeros (I can highly recommend them from previous experience) and the theory stuff through Pro-Pilot (not sure how good they are) then you might be able to get an unsecured loan:

I don’t know the details but as it’s not secured against property I assume that someone will have to act as guarantor for you to take on loan repayments should you default. You might find that parents or family are more willing to act as guarantor rather than risk their house.
