Vacant House with Deceased Owners-->Questions

[Tommy Vise]

I found a Vacant property that is about to be foreclosed upon.  The house owners have both died and no probate has been done yet.  The heirs (3), of the property are wanting to sell it for the payoff to keep their parents name from a foreclosure.  The mortgage owed is $44,000 & the back payments are around $4,000.  The assessment is $89,000.  After speaking to the attorney, the people that are owed any money can put a lien on the home for up to 2 years, regardless of who owns it. 

*****Question: Can I:

1. catch up the back payments, 

2. get the owners to Lease purchase/"Subject to"  the property to me for two years, 

3. I pay the mortgage company the payments, 

4. sub Lease the property and

5.  buy it after two years

If I am missing something, let me know.  If you know of another way to do it, let me know.

Thanks, Tommy V.
