I just entered the details you give into Moneysupemarket.com and they say there is not a mortgage that meets your criteria. They do however give a phone number where you can speak to one of their advisors 0845 345 5705. Go into the website and have a look. You may be able to provide more precise information. If they do find a product for you their fee is �195, paid after completion. A straight loan might be diffcult to find as you do not have the house a security at this stage, as you would have with a mortgage.
