In the event you record a sale the bank may or may not have the right to call the loan due.  

@Antoine Ferguson,Check with the county/tax records as @Michael Ablan suggested. 

You would first need to record your audio. 

However, at the start of 2020, records have been updated, as it now shows one owing $9000 and the other owing more than $11000 (turns out that other liens can be ultimately attached to property taxes if not paid in time—in this case the county wants to recoup expenses incurred in nuisance abatement and demolition).

I suggest building up your list to 1000-1200 records and send mail once a month instead of 250-300 weekly.

Essentially all you are doing is drafting a substitution of collateral contract and a mortgage on the new collateral will get recorded.

HUGE change for landlords in Columbus - Franklin County just removed access to hundreds of thousands of eviction records!

Keep in mind a few things: I kept accurate records of everything.

"In 2016, 110 million Americans had an arrest record with police authorities.That is over twice as many people as in 1997 (when the total was 54 million) and works out to 44 percent of our adult population"....

In my experience most banks aren't searching records to call loans; the .5 to 1.5 difference is probably $35-100 difference in payment.
