Bought in 2021, which major expense is next...

Bought in 2021.
I've replaced the water heater($1200), patched the roof($1500), replaced capacitor on AC($350), found out the AC was r22 coolant and can't be topped-off, whole brand-new roof going on tomorrow ($8000), and gotta pay that off hopefully asap so I can afford to fully replace the HVAC (~$7000-9000)...

taking bets on what breaks next in this single-income household :')
