Slightly off topic here...Your DH saying that "it's his money and you don't contribute" has given me the rage. I presume that you were the one looking after the kids 24/7 (and sacrificing your career, earning ability and pension payments), thus facilitating his ability to work, further his career and get "his" money, without him having to worry about childcare, covering days when the kids were sick etc? How bloody dare he say that you don't contribute!! You contribute massively.
My lovely DF had a high flying job in banking (very high income, lots of work overseas, long hours etc). I'm the 3rd of 4 siblings, and my DM was an SAHM from when I was born (she had worked when my older two siblings were younger but a back injury put paid to that). My DF never ever disrespected the contribution she made to the family as he was very aware it enabled him to be able to provide for the family and further his career, and he made sure that we knew that too. He ensured that her name was put on property they owned etc. He also ensured that they had joint and personal accounts, he paid into a private pension and savings for her (accounts solely in her name) and never once said anything about it all being "his money", as if it were not for her, he wouldn't be able to work in that job. He never once questioned if they needed maintenance work on the house etc. He ensured that Mum got time to go away to see her family, do her hobbies and see her friends. They worked around each other to support each other and were a bloody brilliant team.
I'm the breadwinner myself (and a single mum) and I know the cost of childcare, the cost of having to juggle work and parenting (i.e. when your kid is sick and you have to stay home with them)...and how only now that my kids are a bit older/more independent (and I'm not relying on childcare), I'm able to progress my career and earning potential. You make a huge contribution....don't ever forget it x
As for your house value....who cares? None of anyone's business, so ignore the neighbour! Surely if it is your home, and you plan to stay there long term, it shouldn't matter what it's value is, as long as mortgage payments are kept up etc...it's a home and a roof over your head. Sod what the neighbour thinks!! Are you able to DIY the painting? I need to look into doing some painting in my house! It bloody needs it!
