During this time you are not generating any return from the money invested in the ADU.

I can certainly tell you in SoCal if you had a single family home with an ADU that generates an extra $2k per month in income, end-user buyers will not be thinking "I'd pay an extra $20k for that." 

This either sounds like a seller looking to "retire" and liquidate his holdings or a Section 8 owner that hasn't kept the property (or rents) up to market levels.So, based on the numbers you're using, what return (IRR, Equity Multiple, or ConC) are you estimating you'll generate over your expected holding period?

That’s why I only advertise on Facebook.When you create an ad for Facebook, in the VERY beginning where you choose the type of ad you want to run(you want to run an ad for “Lead Generation” or “Lead Form”), at the top of the screen somewhere, Facebook will ask you if this ad will be for housing, credit, or something else.
