Thanks for the advice Sarah,
I had thought of reducing the size of the house and therefore reducing the morgage I would require, but as I am building the house with the intention of selling it in 5yrs time i reckon a larger house would fetch a higher price! Besides, if I decide in the future to keep the house and live in it I want to build it a little larger so I dont need to build on in the future, economies of scale and all that! I think I am going to proceed with the house as it has been granted on the permission! I will be building the house with my girlfriend and was hoping to get a mortage in my own name, rather than include her on the morgage/deeds of the house at this stage.
My intention was to get a morgage over say 40yr and get interest only for a couple of years to let us get on our feet. Then, if we were to get married it would mean that she would automatically be named on the morgage/deeds. We are both in good jobs and could easily afford a morgage of 250k. Is there anything else that could help my application for mortgage?
Sorry one more question! At the moment I give maths grinds in the evenings, can this be used as income on a morgage application?
