You can google it online to see exactly how but from what I remember it was basically dig a hole, fill it with water, then sit there for an hour and measure how far the water drops every 15 minutes.

I let my tenants know that this is how I measure usage and it is written in the lease that any water usage exceeding 5 cubic feet per person, will be billed to the tenant.  

Buy and hold investors that are truly successful measure their success over years and years 10-20 in my view.

I was even licensed for it in Florida which is the most stringent in the US.

Between the year 2000 and 2006, the gifting requirement was not as stringent, but now with money laundering, terrorist activities, everything is sourced.

Even the attorney who took over the transactions for EquityBuild, who is even more ethical and stringent on procedures than your dad was, never understood what the issue was or what Gordon's concerns were.As Jayne said, EquityBuild produces some great buildings.

What's your favourite measure for the return on your investment property and most importantly why?

I measured it on Google Maps.

The credit score is  a quantitative measurement summer, based on a individuals history, indicating the percentage possibility of a repeat failure to pay. 

Your criteria set is ROI and maybe that needs to be adjusted. 16% is a pretty lofty goal no matter which way you measure your return.
