30,0000 loan or mortgage

Hi

I would like to borrow 30,000 to buy a home with a value of £130,000. I have a deposit of £100,000 (the value of my current home) and no debt or mortgage. I am disabled, unable to work and receive DLA and income support and SDA. None of the main lenders will lend me anything, solely due to being in receipt of benefits, despite having sufficient income to easily afford this mortgage or loan.
Can anyone advise a lender, possibly a niche lender, who may be willing to lend?

Thanks
