What does pre foreclosures Lis Pendens mean

[Tyler Thomas hawkins]

When I search pre- foreclosure on prop stream it comes up with property’s that say Pre Foreclosure “doc type lis penden”

I thought lis penden were liens on a home that can’t be sold until the issue is resolved?

Also are lis pendens property to target?

I’m new to whole-sailing an greatly would appreciate the help.
