Mortgages for students on stipends

I'm a mature postgraduate student on a studentship and receiving a monthly stipend to support myself whilst studying. I currently rent a property but have enough money in savings to cover a 10-12% deposit if I were to consider buying the property, or one similar. As I'm single, I would be the sole person applying for a mortgage which makes things tricky as many banks and building societies did not consider the monthly stipend (which is guaranteed for a specific period of time, like a fixed-term work contract) as an income/earnings. When I was living with a partner and looking into mortgages, they categorised my stipend as extra or additional income. I'm interested if anyone in a similar position receiving a study stipend has managed to find a bank or building society willing to provide a mortgage. Can anyone recommend any which may be more lenient in terms which how they view the stipend (hopefully as income/earnings rather than additional income)? Thanks.
