^^ true. One of the hard truths about home ownership is that things wear out. That 30-year roof might last 15. Water heater might last 6-9 years. Siding can go a while but paint...not so much. AC units wear down, coils need to be cleaned, pool pumps go sideways, etc. etc. And more Etc. And, that's assuming your builder did everything right - I have friends in tract homes who tried to get custom products put in and regretted it terribly. We ordered our first home with two AC units, it was ducted for one. We ripped out the sheetrock and told them to re-do everything - correctly this time.
