We could have a second wave of the virus, and we're still not on an upward trajectory economically.

When you have markets that experience high value growth trajectory over long periods of time, it is always due to market constraints.

If your ready to change your trajectory by opening your arms and embracing a targeted mentorship/training/coaching program, then I'd strongly suggest it. 

The economic hub and diversity of the city have helped our recovery's trajectory be more sustainable.

You'd thought that it would be a better investment than the most established beach areas of Mexico as it is behind on the path of progress trajectory but, in reality, it has been no match to the three powerhouses of Mexican beach tourism: the Riviera Maya, Baja California Sur and the Puerto Vallarta - Riviera Nayarit areas, which likely will remain the best places to invest for most, although some areas of the Riviera Maya are facing overbuilding and other issues.

You might need to bank on appreciation more than cash flow in a buy and hold strategy in most areas, though, which puts you on a speculation trajectory.

Tenants have figured out this upward trajectory and prefer to have power bills rolled in with rent, thus increasing at rent controlled rates (1.5% in 2017!)

However, it seems like the general trajectory is downward at the moment. 

My trajectory was almost identical to @Terrell Garren.

I think it will increase the long-term trajectory of rent increases.
