I'm certainly viewed as cheap by many while in my mind I just place value on different things than others.
This is me too, which absolutely drives me crazy. I know...I shouldn't care what other people this, but it's still annoying. Like you, we don't really value "stuff". Some members of our family think we live in a total dump (their words) because it's not big enough, didn't come with hardwood floors or granite...yet they chose to "downsize" by buying a much bigger house. Would it be nice to have extra storage, yup! We live in a a high COL with VERY high property taxes (and state taxes), so getting a bigger house might be out of the question. Sorry that 2k sf is such a dump.
So to answer your discussion question, no one really knows about this. I handle our finances, with the help of a financial planner, so DH doesn't really understand the extent of it. We don't skrimp on anything really, but we don't need to spend, spend, spend, just to spend, spend, spend. I see other family members with a mortgage after living in the same house for 40 years and are still working somewhat into their 70's because they have to. Yet, they go to Europe every year and buy a new-to-them German car every 5-ish years.
We just had our annual meeting with our Financial Planner, and we are higher in our NW than I thought we were, even with how things ended up in the last month or so. When asked about retirement goals for DH, he said 60 (and in my head, I was thinking..."not if I have anything to do with it"), and I said no mortgage and I don't want to be worried about having to pay for health-care.
In my own personal retirement goals, I am about 10% of my goal, and that is with me being a SAHM. I can *almost* cover my mortgage with a SWR of 3.5%. That's subgoal #1. We keep trudging along with the hopes that as expenses grow as children grow,, I can make as big of a dent now so I can hopefully be on auto-pilot in the coming years.
