Abandoned homes, owners died, lis pendens filed, strategy to buy?

[Robert O'Grosky]

Hi, looking for strategy to buy homes that are abandoned, owners have died, no address, this one does have unpaid taxes, a lis pendens was filed 9/15. Home is boarded up. How can you buy these homes, and or as you find them have a strategy you use to try and buy? I find 2-5 of these properties every month, and someone who is smarter them me buys them at 50-70% below value.
