If you treat your house like a rental that you rent to yourself, you can avoid a bunch of headaches - mainly because you’ve given yourself “permission” to spend on it.
Mine took 3 weeks to replace a broken HVAC when it was 35 degress out. 5 days to fix a toilet that when flushed dumped sewage into my downstairs neighbors ceiling.
Maybe if you're treating yourself as a tenant but your run of the mill rent extracting (or worse, middle man) landlord is the cheapest creature on the land.
Or you do a bunch of shitty halfass 'landlord fixes'
