A great next step would be to find a Realtor in your area (if they're investor friendly or familiar with househacking, bonus points) and they can get you set up with MLS searches and info.

We would also plan to run a cost segregation study to maximize bonus depreciation in the first year.

If you got your license as a bonus to your normal real estate investment career, then focus on building your real estate investment portfolio, find deals, negotiate deals, build a network of tradesman to help you flip deals and sell it or manage it yourself.

Another bonus of managing the property yourself is you'll learn a ton about landlording - and to be blunt... a landlord is going to do a better job than 99% of property managers.

Maybe more chance for value add or some other kind of bonuses like Opportunity Zone, bonus depreciation, cash out refi, and perhaps less headaches once you fund the deal. 

In addition to that, generally for any commission or bonus income you would need a full 2 years in the specific job/industry before you are able to use ANY of that bonus or commission income (There are ways around this if you look at non-conforming options, primarily bank statement loans, but those are going to be higher down payment, higher rate and require a large amount of capital to execute).

You are right that in TPAs there is no upper limit on these bonus ADUs, so long as you conform to the underlying zoning on FAR, lot coverage etc.

New accounts get an 80k mile bonus after $5500 in the first 3 months.

Another bonus to moving Airbnb to top unit is that you do not have to worry about bad reviews from noise.  

I make very good income (over six figures) but because of how much overtime I work (earned around 20k last year in overtime) and from my monthly bonuses (around 60k), I had to pay over $8000 extra in taxes.
