By paying off the bank loan, the seller can avoid the lengthy and costly foreclosure process and can quickly resell the property, potentially to a more financially stable buyer.Hope this helps, and I hope I understood your questions/concerns.Good luck with your class,KC 

Thank you, John.Can I ask one more question,Surprisingly, lender's attorney gave me a contact for pay-off application as a third party that I understood as a purchasing opportunity, but it turned out not possible again. 

Almost all real estate transactions involve a loan, so this is a well understood process.

That's exactly how I understood the process.

However, gaining inspiration on "what and where to buy next" is more of a complexity than i first understood as a wholesaler. 

@Dan Heuschele, understood about the 100K properties. 

This is what the lease says:MAINTENANCE OF PREMISES, TENANT: The Tenants shall be liable for repairs to the premises, fixtures and appliances that are damaged as the result of Tenant’s (or Tenant’s guests and invitees) carelessness, misuse, or neglect.

Understood and will do!

Which is a pretty basic example, but would allow you to monitor the premise, be alerted if there's movement, and record the thieves. 

You are hereby notified that you are indebted to _____________________ in the sum of $__________ dollars for the rent and use of the premises :___________________________________________, now occupied by you and that demand is made for payment of the rent / added rent or possession of the premises within _______ days (excluding Saturday, Sunday and legal holidays) from the date of delivery of this notice, to wit: on or before the _____ day ______________, 20____.Remember, daily late charges at $20.00 a day (as in your lease, after the 7th ) can add up.
