market update from some local experts is below i've seen a few other blogs with similar lines of though and data. seems like there is a little bit of cooling but i don't think we will see any drastic drops in prices in the coming months/year lots of big companies are still moving here and bribing their high paid employees with them.https://www.heatondainard.com/market-update-june-2019/?

Taking a look at the relevant data, the area south of Brookside park is being ranked as a D on an A to F scale, suggesting that the perceived investment risk is rather high in this neighborhood. 

Hi Charlie,I've noticed a lot of your posts seem a bit (different) than most of the other posts in the forum.Are you collecting data (or information) for some kind of study, or writing some kind of paper for some purpose, or something like that?

Other than demographic data, do you know of other metrics that are useful in determining feasibility?

Option 1) Wireless camera that backs up data to the cloud (requires a monthly internet service, which I currently do not have at the complex)Option 2) Camera that backs up data to an SD card (cheap, but I think the card will fill up quickly...like a few days at most)Option 3) Mock camera (may deter crime but could have a liability issue if someone was ever a victim to a crime)Option 4) Do nothingObviously this is not the same as having a home security system as most of us have an internet service plan.

BUT taking the time to show them the data and work through some math with them usually helps things go down a little more smoothly – I've had several clients who started out with a recalcitrant spouse who later became THE family evangelist for turnkey investing lol. 

Based on what empirical data?

But check out Zillow or any other data aggregator.

It means the prospect asset is outperforming the LT-TAV Index of last performing assets.My question is, what are some good indices and their public sources I could consider in order to (1) make my existing indices rich with market relevant data and (2) validate that indices I’m using are productive for measuring risk profile?
