But how do you do that when there's barely any (or nonexistent) cash flow?

You will barely find any duplexes at that.

I assume that you have bare land they rent from you, then they put a tiny home on it.Do you have a lease?

They normally just know the bare basics. 

It's not unusual to have some "accidents" and the smell was barely noticeable.

I can meet the 2% rule (just barely) in my area with a SFR, but I am only going to get $800-900/month depending on the neighborhood.

As such, land in those areas is worth a ton too, whereas land in Gatlinburg has barely appreciated with the market because if it's not something people can rent out, people don't really want it.Short term rental demand in Jackson, WY could die out overnight and a home there wouldn't lose a penny of value. 

You would still choose a property with more value add work needing to be done (and maybe more headaches) even though you have a cash flowing monster with barely any work?

It's still thousands of dollars, and it barely helps.

Vacant Property Coverage offers bare bones protection and can be effective for older buildings sitting idle or when very small self performed renovations are taking place.
