The main thing I see when coming across this is deferred maintenance.

Non-passive to achieve this level of return.Add the addition of the ADU makes the main unit rent controlled if over 15 years old.the work to add an ADU likely exceeds the effort of a brrrr that can achieve infinite return  Experienced investors are adding multiple ADUs by leveraging items like bonus density, committing units to affordable housing, etc.  

I use it for the same reason to build a REI network because I am looking to be an active wholesaler soon.

The main risks I would say to watch out for are any family dynamic issues that could arise as things like this could lead to issues that didn't exist previously.

I am biased but here are a few reasons why:1.

We have our main monthly meeting on the 2nd Tuesday.

I totally hear you on wanting confidence you're getting the *best* deal when there can be multiple that look good (this was actually the reason I built a tool that scans and analyzes every new property on the market so I knew I was getting the best of the best!).

The main thing being: giving up a property that appears to have appreciated pretty well is just a touch pill to swallow and I've regretted a few moves I've made when put in a similar situation to yours, and I had less equity in mine.It sounds like you're moving to Raleigh in the near future and want to buy a multifamily to househack.

It has to be an addition.I would double check because maybe the workaround is reinforcing the garage and building above it.We lived in our studio ADU for two years before we moved into the main house.Best thing to do is talk to an experienced lender.

I believe it is completely reasonable to have a clause in your lease that places a cap on utilities with any overage (proven by a bill) being the responsibility of the resident.Our clause states that any electrical bill (we don't have gas, and water has never been a problem) that is over double the same month's bill from last year will have the overage assigned as a fee.It is important to keep your bookkeeping straight if you do assess a fee.
