Liens on the property. What do I need to know?

[Maria C.]

I just got an email from an agent

"My listing in ... may be falling out of escrow.

The 1st lien has approved this at $350K and the 2nd Lien at 10K.

Please let me know if you are still available."

The property is for sale for $300K. Looks like a usual sale. I'm ready to pay not more then $250K cash so the numbers will make cense and I can close asap. 

Do you think it's possible? What do I need to know? It's a first time I will deal with liens.

All help will be greatly appreciated.
