Not saying it doesn't exists...I'd just be very curious how they are managing their business.

In your post you say that Trump assumed the loan when he bought the property but mention in your next sentence that the bank didn't know about it.This means that Trump bought the house "subject to" the existing deed of trust without the bank's permission.When a person "assumes" a loan, they are getting permission from the lender to step into the borrower's shoes to take over the loan. 

I'm curious how others handle this circumstance or if there's a network that already exist. 

New builds - existing lots - in less than 1-week.4.  

I certainly did not, and neither did the mortgage lender who  pre-qualified me.After closing on the HELOC  this week, I was reading through the docs last night and stumbled upon the Occupancy clause :"Borrower shall occupy, establish, and use the Property as Borrower's principal residence within 60 days after the execution of this Security Instrument and shall continue to occupy the Property as Borrower's principal residence for at least one year after the date of occupancy, unless Lender otherwise agrees in writing, which consent shall not be unreasonably withheld, or unless extenuating circumstances exist which are beyond Borrower's control"So I'm not sure what to do.  

Steve & I are working on several existing production oil deals.

@Nicholas Lohr I'm not sure that this type of data exists, although I could be wrong.  

There exists a significant problem in district court procedures that we must all be concerned with.

don't let that entrepreneur mindset forge bank statements saying that you are a cash buyer and have $100K available balance with Citibank  (while in reality neither the balance nor the account number does not exist) I receive 2,3 offers daily from "wholesalers" who think they know what they are doing. you too pretty for jail...

That has been the case for the entirety of it's existence.
