The second option, what if I were to pay the property taxes to date with the permission of the owners and essentially send the property to foreclosure as a lien holder?

Should we be named as certificate holder ?

We have multiple employees with multiple different credit cards (Home Depot, Visa etc) for our business.

As I read through them however, I did not find any information regarding my latest question regarding approaching a mortgage holder before a sheriff's auction and trying to assume a mortgage.

Financing the sale of a contract may not qualify as a RE secured note.To obtain passive income, you'd be the lender/note holder and all of that is not simply passive income, some will be capital gains.My first impression is that you need to learn more before you try hitting the streets, RE and especially financing isn't just shuffling deals and papers around like the gurus suggest.

We also request a copy of their visa. 

The Due on Sale typically says something like "upon change of equity holder, change in title". 

Most lenders will require some sort of VISA, and usually some reserves in a US FDIC insured bank. 

The Ownership Certificate will show the name of the registered owner and the lien holder (lender/seller).

The seller (who is the most senior debt holder) is considering putting the property in receivership.
