Additionally, it feels the most appropriate approach for both profiles I described above and allows me to focus on learning one strategy.

You need to minimize upfront expenses because 100% of your investment is at risk and lost if the lot is not buildable.My favorite strategy is to locate the property and tie it up for usually no more than $100 for a period of 8-12 months, analyze it myself and if I believe it to have a chance at being buildable I create a permitting plan and market the property to other investors/builders willing to take on the permitting risk.

This gives much better diversification protection across geographies, asset types, strategies, investment subclasses etc. versus putting all the eggs into one basket.The downside is that it's not for everyone, and a person has to be comfortable with turning over control to someone else.

There's a lot for nuances to the strategy than what I typed out, but this should help you get started.

Just depends on your strategy but my best advice is to take a drive through those areas.
