I'm lucky because my rent is only £91 a week,I don't drink or smoke anymore,no kids and my missus has her own business too. No way would I be able to lease a new car every 3 years if I was paying private rent as it would get swallowed up in rent. I also save regularly too in my instant access ISA and various other high interest accounts for tax/NI,holidays,emergency fund,etc
When I move in with the missus I'll be no better off. It'll be about the same as I am now living on my own but my missus will be better off financially because I'll be helping with the mortgage and bills.
My missus has spent a lot on the house over the last 10 years,new driveway,fencing,large summer house,new shed,lots of painting and decorating,plastering,new furniture,etc,etc.
She feathers the nest and I pay for the holidays and do most of the cooking.She ll be mortgage free in a few years so we will both have lower outgoings.
Health permitting I can see us both working in some capacity (albeit
part time)well into our 60s and 70s...
