Come on downvoters: surely your super solid argument can withstand my accounting records. Tell me what I'm missing as someone who owns the very sort of building I rented in for decades under maybe 10 landlords– both good and bad– at 10 addresses! What haven't I learned from that and the many people I've known who've owned rental buildings for decades? Surely the family whose bar I cooked in that owned 4 or 5 buildings they maintained themselves (even illegally doing things like replacing gas boilers themselves) was somehow hiding the labor they put into it because they all spent almost all of their time running the bar? Surely if you feel that correct, you've got solid empirical evidence that opposes mine, right? Expenses and labor are cut-and dried and any responsibile business owner documents them, right? This should be an easy argument to prove me wrong in.
