The second you are introducing metrics to change your marketing that have nothing to do with generating the leads you need, you introduce uncertainty to your systems. 

- What metrics do you use to measure "good"Ex "Hi I'm looking to buy a single family home in Richmond TX in the $150-200k price range.

For rentals, focus on cash flow and metrics like cap rate (target 8%-10%) or cash-on-cash return.

This goes back to the aspect that you can't rely solely on one metric. 

I think what you're really asking is how to identify good value areas where rents may be trending upward but the prices still remain relatively lower.An important metric is tenant household income to rent ratio.

Prioritize deal analysis with metrics like cash-on-cash return and cap rate, and always account for expenses and due diligence.

I haven't seen any quads in our metro make more than $2k per unit (unless in 78704), let alone $7k, so not sure where those metrics come from.

I paid for the subscription for a few months and drew my own custom Google maps areas and color coded them red/yellow/green based on a "grade" I felt came from a few metrics like crime/average household income/etcI also really like realtors dot com new maps, if you search for an address and click on the map and then go to the top left and choose the Value slider it will give you a nice color coded map of which areas of a neighborhood are higher valued.

Measuring the input is the only metric that can be controlled.

It is possible that over time, Google ranking metrics recognize the uniqueness of your key words, and you move up in the rankings organically (without a cost to you), so that you can be found easily on Google searches for your location.
