NP here.
Living in NoVa, the car thing is really, really tough. That's one of MMM's key points. Me and DH are definitely "car clowns."
Car costs are killing us here, even having paid-off cars. Public transportation not an option for DH, or for me since we have to tag team.
We are able to do some things:
Renting the cheapest acceptable place. Plan to buy because we plan to be here long term, and having a paid-off house is valuable in retirement. Long term, you'd have to be truly saving a lot of money renting to make renting the better option. Rents go up, up, up every year. A mortgage payment will stay the same and then when you are done you'll have something to show for it.
Eating at home, and packing picnics for outings, attending potlucks with friends. Hello H Mart, and Aldi! And not eating a lot of meat.
Buying kids clothes at resale - though mine are young now and don't care, I can see how this will become more difficult.
No gym membership or any of that foof.
Public school.
Kids have been raised to not expect new toys, latest video games, etc. They don't even ask for it and entertain themselves just fine.
I am low maintenance and always will be - jeans & T shirt lifestyle, unless I land a job that requires more.
But again, the cars are killing us!
We could move closer in but the difference would be made up in more rent or a higher mortgage payment.
