Yes the other parts like being in control are valid for experienced investors, I'm just too new to consider spending tons in renos and flips, something I know nothing about since I'm not from this industry.Another potential problem is that I'm in Canada (stocks invested in the US as I used to live there), which means that I struggle to find positive cash flow properties.

Moen makes good products also and cartridges are all a swap for those (warranty).
