How would the bank proceed with the heloc app in this case and anything I should do to get the loan finalized? 

Does he have one of those dash mounts for his cell phone?

Your post brings up the 2nd subject and that is; it is counter-productive to remain anonymous because the very first thing every person wants when doing business with every business is they want to feel secure and want to know that when (not if) they have a problem there problem can be solved easily without having to jump through fiery hoops like a circus dog.We own several apartment buildings and we give every tenant both my wife's and my office numbers and personal cell phone numbers.

Is there an app out there?

Do you have a recommendation for easy to use website/app to track my expenses, bills, etc?

I am exploring property management software/apps and came across RentRedi, which seems awesome.
