You'd look at historic patterns and owner/occupant profiles, we don't have enough data points to figure the probability but 1.2% of profit is an acceptable known risk by most standards.

I look at this map and I know there's single family homes being build in all of these areas but probably not enough to create a positive migration patterns. infill is tough. some of these aren't residential zones like south side the two zones are heavy industrial sites 

No set pattern.

Something I've seen done is to look at the listing agent's sales for the last 12 months, compare list price to closed sale price, and spot the pattern.

Then as you find patterns, use lists to find all the properties that match those patterns.

We get a lot of our data from title companies, the biggest being Black Knight, Inc.I work in 30 different states and see some patterns in property value but there is only so much you can do from a computer.
