Any advise is greatly appreciated on the subject! 

i would speak to your cpa, as you may be able to get all or most of the gains tax free if they lives in it two of the last 5 years. vs what you can get if you rent it outof course consult with your cpa for tax advise

Does anyone have any advise on the area or some good resources?

Based on what you're telling me, I'd also advise you to begin the process of evicting/non-renewing the lease.

After 40+ years in real estate sales, management, and investing, I advise someone in your situation to cultivate your patience.No market moves in a straight line--they move in cycles. 

If the numbers work, it could still be a great opportunity.If you need local advise, I’m happy to help.

Could anyone please advise a good management company for mid term rental in Arizona?

I wouldn't advise pulling a HELOC unless your numbers are dialed in and you are willing to take that risk.

I was advised people if you have 25 or $30,000 put it in a deal and learn from there but don't give it to a guru. 

Please advise.
