I believe that's a jurisdictional issue. 

I believe in full disclosure, so seller is fully aware of my intentions and in agreement.

I got in at a lower rate on the duplex 10 months ago and if I refinance, I’ll lock in almost 100bps higher rate (I believe).  

I'm certainly not an attorney, so not up to speed on all things legal, but in my small brain way of thinking, if HELOC loans are not allowed on Investment Properties in Texas (by Texas Law), I find it difficult to believe PenFed is doing HELOC loans in Texas on Investment Properties.

While I've never lived in Phoenix I find it hard to believe that Tucson has a lower affordability rating than Tempe, Scottsdale or Phoenix proper.

Believe me, when the roles are reversed and you are paying 1% on your primary residence that was once an investment no one will be making a claim of it is illegal, especially the bank as they collect a higher interest rate.

If there's a stone you think was left un-turned, believe me we've turned it over a dozen times.

I believe to be emotionally invested in this because I found this property myself.

Quiet title actions allow parties who believe they have remaining claims to state their cases in court.

I have since found out that other tenants on the park pay for their own monthly maintenance sprayings and have been doing this as a matter of choice since they moved in to make sure they don't get any issues in the first place.I also have 3 SFH and 2 of those tenants (also inherited) have their properties sprayed on a monthly preventative basis.I would be interested to hear how other landlords treat this issue and who's responsibility do you believe it falls upon.
