The 9% mandatory property management fee eat up a lot of your profit, so I give up all multi-family in Las Vegas. 

I would have thought they would have given you a labor warranty with a new install, so maybe the dirty coil claim was to cover a deficiency in their installation that they would have had to eat as a warranty.

My fear is worn out stuff like HVAC, roof, or plumbing eating future cash-flow.

One issue from this could eat an entire year's profits.

If you end up in court the debtors attorney will EAT YOU ALIVE.  

5.Any good places to eat/drink and places where I can just talk to the locals After my trip, I would also be happy to share with you all what I learn!

Termites do not eat just wood, they eat books, cloth, and yes, concrete as well as a mean for a path to get to the rotten woods or desirable termite diet.  

Of course I also had a mortgage/rent to eat some of that up.

@Josh ThomasI strongly agree with @Nathan G.I know paying for a vacant place for 3 months in another market is eating at you and your wallet and who could blame you, but dont rent to these tenants on a emotional decision of being 3 months vacant and not wanting to go a 4th month vacant.

Interest rates can eat up the little cash flow that you might be receiving with the additional purchase, and wipe away most gains that you receive from the initial properties.
