So more risk / work needs to = more reward

I have never been one for transparency in the past, however as I read in Michael Zubers book you will not be rewarded for being silent in this business.

Inflation punishes savers, rewards borrowers.

If you see a good deal, buy and hold a building with upside and the bay area market will reward you in the long run based on history.

For sure picking the right roommate is  key and can be so rewarding .

There're more negative story in this aspect.As summary, from investment perspective:  building ADU is a "good" speculation with possible reward, if you're lucky enough it may be good for you if you meet your objective and financial/non-financial goals.

For a place where prices are geared very much towards appreciation and not cash flow, I think the risk is outweighing the reward. 

Policies that make housing more affordable in a variety of neighborhoods “separates effort from reward.”

If you focus on helping homeowners solve their problem you’ll find that they will reward you with their business. 

Cash for keys will cost you money AND it rewards the Tenant's bad behavior and encourages them to do it again.Your PM is correct.
