There's also a detached two-car garage and workshop.It exists in kind of a twilight zone between commercial and residential.

What obstacles did you overcome?

I love it when I see other investors make it happen despite innumerous obstacles in your way.

I think it's probably less common here but I've often wondered about how difficult it would be to convert a detached garage, etc. on a property from a legal standpoint.

The property is in an evolving area with an overlay for Detached Accessory Dwelling Unit.

A licensed agent can do all the things a wholesaler can do, and is a proven business model where the same hustle that any successful wholesaler brings to the table can be rewarded 10-fold more, with little in the way of legal obstacles.

A trustworthy agent should make the process clear and help you see the properties you're interested in without unnecessary obstacles.

Another one had a detached garage that was not on the property. 

I plan on doing this model also so I would love to follow your journey on this investment and learn what obstacles you may deal with.
