Liens on a Property

[David Rogers]

Hello biggerpockets!

I'm considering making an offer on a property but it has a few liens on it. I'm wondering what I would be responsible for paying and how I could use the liens to my advantage at the bargaining table. They are the following (abbreviated):

1) Taxes and assessments for 2015 - $10,000

2) Open-end mortgage - $65,000

3) Mortgage - $75,000

4) Collateral assignment of leases and rents - $91,000

5) Open-end mortgage - $91,000

Is this something I should still bid on? If so, do any of these liens give me the clout to look for a lower offering price? 

Thanks!
