A secured loan is still 'doable' for that ammount.
Seems a bit obvious, but do a search. Moneysupermarket.com springs to mind.
There is always a shark out there willing give credit if your house is big enough.
Obviously, the devil is in the detail. Don't expect a decent APR. And don't be surprised if they ask for you to have a lot more equity in the property than the loan amount to cover their arse in the current world of house price deflation.
Topic drift I know, but is this the best move right now? I'm certainly not a doom merchant but now is not the time to have to sell a house.
It sounds like you are funding an integrated course on 100% secured credit. Think about it.
