No chance of a mortgage if gambling is your only income.
Had a "life review" at the bank last week with regards to long and medium term savings and they would not factor in future earnings from "sports trading" as it was not guaranteed income. He did also say that this applied to playing the markets or futures too.
The irony is that it is the very money I have deposited in savings from gambling that prompted the bank to discuss a more rewarding investment!
