You're at the net worth level now where detailed investment and tax analysis can have large impacts to your overall ability to retire and spend. 

We are managing the units ourselves so we're thinking optimizations like this will simplify the process and create a better experience for the end tenants?

Ensure strong reviews, professional photos, and optimized listing details to stay competitive.

If so I'd lean on that and maximize the piece that creates the best ROI.

I was pregnant with my first son and my husband was in school, so we needed somewhere to live that could pay for itself and create income.

HELLO JOSE DM ME FOR MORE DETAILS.

(All of this is also with the caveat that I don't know the details on your current home). 

The property aggregators (Zillow) etc are good for high level comps but miss key details such as concessions & amount, private remarks about the property that materially impact value (for ex. solar panels are leased w/ 20 years remaining) and limited pictures of the property.  

Really pumped you introduced yourself.. how comfortable are you with analyzing cash flow details so far?

Do you have the ability to create the ADU yourself by converting the garage?
