I ve tried to find such lists online in the hopes it would be public information as most things are today, but had no luck.

@Richard Morency I am sure if you look hard enough online you can find some scripts for all different scenarios.

At the moment I am very overwhelmed with all of the information that is available on this site and that is available everywhere online.

You decide.....If you decide to not let them slide out early without penalty, just make sure you have everything documented really well....dates, reports etc.

I have access to all the documentation online and Wayne has been very forthcoming with answers to all my questions. 

If you use an online mortgage payoff calculator with $280,000 at 4.8% for 29 more years, paying $2000 extra principal per month, which is less than the $30K extra you say you'll pay annually with your line of credit, says your mortgage will be shortened by 21 years and save you approx $178,700. 

We have since defined the listing date to be 4/10/2018.
