Although the forum input can be helpful, you need to have proper legal precautions in place rather than opinion.

In San Francisco proper the discrepancy between 2 and 3 units is bigger I assume because of condo conversions.

Its essentially in the longterm best interest of the property owner to ensure there is a non-compete clause in all leases; merely for the benefit of securing longterm relationships with the tenants.A diverse tenant mix can attract a wider audience and contribute to a more vibrant environment.

@Evan Polaski It took me at least a year of sourcing sponsors, finding investment group resources, analyzing opportunities, and understanding proper diligence; so, following a sponsor for a long time happens in the ordinary course of getting familiar with an investment strategy (particularly one that lacks control).
