Patrick,Just a heads up, no lender that I have found will let you do a HELOC on a rental property.

Excessive holes in walls....you mean from nails after art is taken down for instance?

There will be a lot of people getting bids and getting all hot and bothered, but not everyone in the state will rush to build these once reality hits.Off the top of my head around 15% of all new homes in California are ADUs, and it's increasing every year. 

@Barbara Pinto No problem, you hit it on the head with what to account for and as long as the numbers in returns works for you and you are comfortable then all is fine.

Again, I hope this story touches at least one person and encourages you to take on those "scary" challenges and take them head on! 

Heading back in November and leaving again in January.

With a multi-head mini-split, each room can be individually controlled.

One thing I can't wrap my head around is the fact that the more properties you purchase, the more debt you go into (assuming you are taking out a loan to purchase each property).
