Homeless because of your insurance

I'm about to be homeless, looking for an en-suite only, a bedsit, a flat, or a house rent for at least 6 months because my current landlord has sold my property. I am on Universal Credit but I can pay 6 months rent upfront and a deposit. No one will give me a home because I either don't have a guarantor, or your insurance company won't allow it. I can pay 6 months rent upfront and a deposit. I'm clean, quiet, no pets, and don't smoke. All I have met is pure discrimination. Landlords would rather have their house sit on the market for 2 years before taking my money. Where is the logic?

If there is anyone with sense out there that can offer me anything in Cumbria or around Dumfries, I'd fall off my chair.

Thanks
