Lien Piurchase from Previuos Tax Years

[Ben F.]

Hello,

Any advice on purchasing tax liens from the prior year versus the current year?  I know the most preferable investment is purchasing from the current tax year, if you are looking to profit from the interest for a faster redemption, but would there be any advice when looking to purchase liens from a previous year? 

Primarily, I am looking for the owner to redeem but I am open to considering a method to pursuing the deed if the owner doesn't redeem.

Thanks in advance.
