I really like this one, I'd probably sell it, 2.5 - 3 million would sort all the kids out and ensure a lovely financially worry free retirement for me and DH.
I could be tempted to keep this one for a couple of years, run it as a holiday let for most of the year, and keep a few weeks for family and friends to stay in it. As long as it paid for itself, with maybe a bit of profit, I'd be happy.
I like the layout, and with 5 bedrooms there's enough room for the whole family to stay. All with en-suites means no arguing over who has the best room.
TBH, I'd love to live there, but it seems selfish when my kids are struggling to buy a small house.
