This analysis is rough, so there likely isn't anything special about these particular zip codes, but likely here and nearby will be more fertile statistically for 1% houses.If anyone is active in these areas, I'd love to connect and talk about your approach.

You will know exactly what is in each house, what the measurements are, etc. this means that if you have many you can have a standard depreciation schedule for them, it also means you can track statistics on repairs (a quote for a single home is completely applicable to any other property), how long appliances last, etc.
