One of the tenants has been causing issues with other tenants.

I've been deliberating over the same issue (long-term rentals vs. medium-term rentals) and am inclined to invest the extra effort to manage a medium-term rental, given the appealing additional cash flow it promises.

My house is on a corner with an empty lot next door, so it was not an issue for me.

The best part about Reno / Tahoe Nevada are it's landlord friendly, Real estate taxes don’t reassess on the sale, insurance is low and we continue to have increased in migration, jobs (no state income tax) and our own land constraint issues which prevent the market from getting overbuilt. 

If I cashout refi one property , that would resolve my debt issues, but I'm torn.

We've had issues with Mario and his various business ventures. 

Check your local building permit department.  

Too many potential issues with the younger crowd.

Maybe print the pricing off of their website and keep it as well in case there is an issue down the road."

I got another master gas tech, as a second opinion, who fixed the issue for $50, as it was a leaky stove.
