Just out of interest, why are you selling your house?Going from previous threads and Royal Navy advice, they advise not to hand any notice of resignation until you receive a formal offer within phase 1 training. Hope that makes sense?
Good luck with your application.
Have you investigated changing your mortgage to a buy-to-let & renting it out whilst you live courtesy of her majesty.
Then it’ll pay for itself & you’ll have much more equity when you need to live solo again.
Many poor sods come out never having owned a house, or, having inadequate savings for a deposit. Renting it for now would be a ‘win-win’ for me personally.
Just trying to help if you haven’t considered this option.
I rented my house out whilst posted abroad & paid a huge chunk off my mortgage by just paying all of rent to mortgager (bank / building soc) within terms of ‘allowable overpayments’. This enabled me to buy a much better house, on my return, than I could have afforded otherwise.
