Approach to Lender for Pre-Foreclosure Property, w/o Owner

[Chuleung Leo Joo]

I am currently live in an apartment that was leased by the condo board.  Owner has been missing last decade without paying mortgage neither maintenance that legally supports condo board to leasing the space to a tenant.  Recently, many legal paper works delivered to my apartment that was intended addressed to the owner, informing foreclosure process due to unpaid mortgage.

I want to buy the apartment before it goes out to foreclosure process, and I've called the the lender side lawyer, but it wasn't successful obtaining proper contact to the lender who I can initiate deal discussion.

Could I ask advice how I can effectively approach to the lender on this purchasing deal, when owner is not available.

Thank you, in advance.
