I also have a development project on a condo that is about to break ground in Mexico. 

The appealing aspect here is the ongoing population growth and other economic factors.

Prefer area with population and job growth potential.

Building small units in small unit count is some of the most expensive development.  2) the financing on an ADU is typically far worse than for initial investment property acquisition or is often not leveraged (HELOC, cash out refi, etc).

The population is growing, the job market is growing, and there are so many major companies moving and developing out here like Intel, Amazon, Google, Meta, etc.

City officials plan to make the Queen Mary a centerpiece of their Olympic tourism strategy, alongside hosting five Olympic events.In addition to refurbishing the ship, Long Beach is developing its downtown and waterfront areas, including a new amphitheater and commercial spaces.

Seems like the city is projected economic development from hospital and Honda plant .

Do I have to rub elbows with Elon to get insider development info?

Most of us doing it a long time have developed systems so that we handle these things efficiently.  

High appreciation markets have low cap rates, good population and job growth.
