I just launched one in Tempe. 

It very well could become a large enough investment to be worthwhile, also solving for "unexpected emergencies ", for the most part and would an easy self management situation if you were to live onsite in one of your connected townhomes.

I just did one, so I know this is a fact.

However, not one general location is going to help you determine whether it's a good market for multi family or single family etc.The one true way to start looking into a market is talking to an agent who knows the area.

Was at one last week that included City of Calgary who did a presentation on legalizing illegal suites and accessory suites in general

I own several in Alabama, including one in Bham.

Case in point, I picked up some turkish blankets with great color and pattern on Etsy that looked awesome in my photos, and one of them was gone by guest #3.

One with low cash, one with some owner financing and a little less price. 

If there’s physical damage dishwasher goes out 3 times in one year like it has in the program I work at the company pays the first $500 towards repairs or the new one.

I spend $90 a month for one LLC, and $50 for another.
