This data set would be a metric representation of the market direction and strength of that direction, be it growth, decline, appreciation, depreciation.I created my own algorithm for calculating such data and disseminating it into a charitable data representation, but that is just me and my own understanding of how I feel things should be weighed and measured.

What are you using to measure what general contractor to hire?

Are there certain ratios one should use in order to measure whether or not a real estate investment is wise?

The index measures the number of months it would take to sell the supply of homes on the market at the current sales rate.

This is a place to measure up balance sheets and peacock, it’s a place to genuinely help or ask for help.

It's a good safety measure because, like @Jeff Rabinowitz pointed out, you never really know if you got all the keys back. 

I would be the pass/fail rates are very similar if there was a way to measure it.  

These include the allowable annual rent increases, bond measure  passthroughs, water revenue passthroughs, capital improvement passthroughs, rent board fees, banked rent, etc.The other thought is that if you inherited this property in the most "vanilla" situation, you may want to consider selling it because 1) your NOI is going to see a big impact once the assessed value is reset after Prop 19 and 2) you have little to no capital gains as the property's cost basis should have jumped up to current market value.Just my two cents...

Anyway, I seriously doubt that any investor will need to convert links and chains to meters or feet (links and chains being an old survey measurement).

Let's also not forget that cash flow is in no way the only factor to consider when measuring returns.As for the legislative uncertainty, I feel as though it's better to invest places where a dialogue about STR legislation has either already happened or is currently taking place, rather than areas where those discussions haven't yet begun.There isn't a single city in the US that I'm aware of that you can have complete certainty about their future legislation on STR's.
