This may very well be the first story of many of why they can't pay their rent on time - bank issue, health issue, pet issue, etc, etc, etc. 

So tell your agent the deal is dead, they did all this work and won't get paid, unless they get a signed agreement from a tenant agreeing to vacate by 7/31/18 and your bank needs it by Wednesday

My current lending bank basically just told me, not to my surprise, that there is not much room to refinance and take money out.  

It seems that banks won’t do a HELOC on an investment home (primary only).

My bank will not do business with me.

, but in my opinion you should treat investor funds no differently than you'd treat the bank's money.

Could anyone direct me to investor friendly real estate agents and banks in the areas?

When we have the next correction you will see a lot of buildings going back to the bank and forced exits from owners/management companies that do not know how to operate in a slow market. 

Go to a big bank like Wells Fargo, they do 75%LTV on cash out refinances. 

I tried getting a HELOC since I had so much equity, but I stopped looking after a couple of banks because I did not have the energy.
