Moderator, we have no financial relationship with any guru :B ] after we canceled promptly there were no additional billings either time.

In addition to that, platforms like HomeAdvisor or Angi are great for finding vetted professionals, and local builders associations or the Greater Beaumont Chamber of Commerce may have directories or recommendations.

Here is a list of what adding ADUs in my CA market is typically a poor RE investment:1) The value added by the ADU addition is often significantly less than the cost of adding the ADU.

I do not see that home prices have dropped 2-3% and this is a lot of added savings in additional to a downpayment if so. 

The cons as i see it include loosing the 2 of 5 year cap gain exception, typically not an ideal rental because the emphasis at purchase was buying a good home for your family and not a rental with optimal return (my ex-home consistently has the lowest cash flow for equity in my RE portfolio), not disconnected enough from the property causes addition angst on damage and may result in over improvement.  

Quote from @Don Miller: The following is not to express any level of happiness or unhappiness with the build:Received change orders totaling $14,970 for 18 additional loads of fill dirt over allotted amount in contract (fill dirt arrived in December 2022), 7 loads of septic sand over allotted amount, and rock excavation at the septic site.I deal with all of those issues on new builds.

When its included in a lease for real estate then the laws pertaining to residential rental security deposits in your state apply but when its separate you should have more leeway to get some additional deposit to protect you.
