+1. Just do your months worth of DD beforehand so you can eyeball 90% of the DD required within the first few minutes of researching a property.
Or as also mentioned, pay/pester someone who can do it in 30 seconds to help you out.
You have to learn enough about doing the development DD process so that you can basically do the property-specific DD required in one day.
Plenty of stuff like the Rcodes and estimated construction costs can be essentially eyeballed once you know them well enough.
