I'll give you another angle.
I left aviation for three years, when I was only twenty hours away from my CPL. Had I finished back then, I might be an Airbus340 Captain now. (I might not have been of course.) I worked as a taxi driver (very fun, funny work), in sales and as a bookshop manager.
I think that your best bet if you want to be a professional pilot is to sell the house, (one less debt and savings back in your pocket.) and go for it.
STAY IN THE INDUSTRY.
You will make it in the end, as you already seem well on your way. You might get your dream offer next month. Or, if you are in a dingy office doing IT, they might decide that you don't really like aviation after all, and give that corporate/airline jet job to someone else.
Good luck
