You want a list that is difficult, uncommon, and/or takes some time and effort to compile yet is still effective, that way not many others will be hitting it ... one example is driving for dollars to build your list.

Compiling all of this must have taken a considerable amount of time.

I am trying to compile all of this data so I can keep track of the trend and possibly use it for some capital gains in the future.The 5 metrics are:existing-home salesnew home building permitsmortgage loan defaultsforeclosure salesinterest ratesThis is the first time I have really dug into data scouting and I think it will be a useful skill set, once developed, because I am looking at getting into note investing in the next 6 months and using the cashflow from those assets to accelerate my SFR buy and hold strategy.

Land cost's can rapidly adjust and step down from some insane highs, where as replacement costs compiling of the dozens upon dozens of inputs to such, provide a much more stabilized potential of adjustment.

Thank you all for the advice, I've gotten keywords setup and I'm compiling a list of topics I want to dig deeper into as I read.

However, I was brought the thought of working with a compiler through one of our junior guys (who didn't understand it) and as it happens that we have a friend who does a lot of foreclosure purchases, it seemed like a good fit for him, even if it's a bit out of my normal realm.

I think your best bet is to find an investor-friendly realtor ("investor-friendly" is important) who can help compile some numbers for current deals on MLS.

The survey compiled by https://ocindex.net/rankings ranked all nations and The US was the 129th safest place to live.

I read one of your comments that finding buyers will be the easy part, once the numbers are compiled and a solid deal is put together.
