Regarding which department at WAB, I would call the servicing department and ask them for who to contact to release the lien.

It looks like there's a mandatory capital call forthcoming in a project I'm an LP in.

They almost never answer but if you leave a message with your contact info and property ID number (located on the form) they will call you back. 

Drive for dollars, cold call, door knock do something to find a deal and when you find a deal the rest will follow!  

From a seller's perspective- They do not want to upset tenants and want to avoid what I call lookilous.  

For online rental payments I use Apartments.com as it's free for both me and the tenant and they have good customer service when I call them. 

Brandon Turner has a great webinar called Househacking 101- probably right up your alley.

Sometimes they actually call and I mostly politely declined in the past but they just kept calling and calling so then I just started going on and on about how I need to sell this property at above market price and make a lot of money from them.

They are very worried about the subject to clause and I thought I remember the podcast mentioning insurance policies for this in case the mortgage company calls the loan due.

Call them up and ask them if they’re looking to expand their offerings because you have properties available for them to rent.
