Also just to run some numbers, it required a substantial amount of money. We had to put 36% down in cash (a byproduct of both of us having quite lucky lives before meeting of high salaries, a penchant for saving, and no financial emergencies) and paying about 40% of our take home pay on the mortgage the first 3 years, finding the Mister Money Mustache blog and then upping our contribution to more like 65% of take home pay.

Our sacrifices were more the likes of no eating out (but still eating healthy at home, protein when we wanted it, dinner parties as well), shopping around to combine our insurance policies, waiting much longer than normal to replace cars, appliances, or gadgets, but mostly related to just having the higher than normal salaries with no kids until only 1 year ago.
