We’ve sold our house and have had an offer accepted on a property in an expensive area of a very expensive location. It’s an extremely modest property that needs work but we got a good price. Our current mortgage is 16% of our net monthly income. The new mortgage would be 40% of our net monthly income.it seems terrifying. After the mortgage and council tax we’d have 4k a month to live on as a family of four. I own 50% of another property outright and have ~45k in savings, but my contract for work only lasts until Feb 2028. Are we making a massive mistake taking on such a massive mortgage?
