I told a realtor I was interested in one and she told me the board may not allow them to be rentals.

With our 4 bedroom home we allow 10 or 12....forgot now.

What's your thought about the ability to retain the customers and replace the main person? 

Cashflow for profits (Like I mentioned before, worst case is to break-even which will allow me to control a desirable property that essentially pays for itself after initial cost to build.

Hi Siyi, something powerful that you can keep in the back of your mind: My understanding of California's ADU law is that it requires all municipalities to allow conversion of any single family home (SFR) garage into an ADU.You mentioned that you're looking to house hack but don't feel comfortable having renters in your space.

House hacking is always a safe bet, which should give you plenty of possibilities and allows you to put a much lower down payment. 

I'll only have to pay monthly rent and an option fee to move in, and I plan to find tenants and charge them a monthly rent that will cover my rent and allow me to live there for free.

I disputed the reversal and Buildium let me know that their policy allows account reversals up to 24 months in arrears.    

Allow me to impart these valuable insights to you!
