Your bio says "Denver" but that could mean a lot of things and there are significantly different rules on renting out your property whether you're in Arvada, Westminster, Aurora, Denver proper, etc, etc.

Quote from @Christopher Berra: Quote from @Kevin Perez: If you want any advice feel free to reach out all of my rentals are S8 in several different states - every state has their own rules and guidelines but reach out if you are still interested What has your experience with Section 8?

You have no idea if they are following the law, AirBnB rules, paying taxes, etc.

I know Chase has rules, I think it is 5/24. 

I would also be worried about the park rules and keeping my guests from breaking them.

That means no HOA neighborhoods, which rule out many places.  3bedroom might make it tough to work, unless you're sleeping in the laundry or garage and renting full 3bedrooms. 

If you see someone violating the rules, create a post with "@moderators" and we will receive a notification and respond.Again, welcome to BiggerPockets and happy investing!

A standalone ADU is almost always going to cost more than doing an addition, so the value added or cash flow increases will have to justify each.I work with a team of investors who will buy SFR homes then build a new ADU on the lot and add a separate drive way and meters for utilities in North Texas. 

@Robert SandovalHave you looked into the rules and laws in CA for what requires a broker's license? 

If I assume a 2% rate of rental increase for 15 years and 50% rule for expense, we will have $7.5K/month net-profits in 15 years.- Split 50:50 between real-estate & stock market.
