Hi Guys, I just wanted to provide everyone with an update. All your advice has been really helpful and I wanted to say thanks to you all.
We are now looking at spending May to October 2023 in the UK. We will rent our house out and treat it as an extended maternity leave for my wife and a sabbatical for me. We've cleared it with our employers that we will have our jobs when we get back.
I'm hoping the rent will cover our mortgage but I am keeping a constant eye on interest rates (that whole situation has me worried).
My mum has agreed to host us, she lives alone and has 3 small spare bedrooms so we will just about squeeze in. (will be my wife and 2 small children)
Im hoping to buy a (very cheap) camper van for the UK as I don't think I could spend 6 months in my mum's front room. This way we can be around for most weekends but during the week when people are at work we can go on adventures around the British isles. We are very excited.
We won't have a massive budget but this really will be a trip of a lifetime so quality time with family, camping adventures around the UK and perhaps a couple of trips to the continent. Maybe even a music festival.
Let's all hope everything fits together and we can pull it off.
Thanks again for all your help.
