How likely is a lawsuit to occur in a Trustee Sale?

Based on your experience, how likely is a lawsuit to occur in a trustee sale? 1%, 5%, 10% of the time? Also are there things to look out for in advance that would possibly lessen the likelihood of these type of situations like buying vacant homes only? Please advise. Thank you!

My experience was around 2%, a little higher if you include problematic unlawful detainer (eviction) actions that required an attorney.

If you can keep a cool head, most get resolved fairly quickly. If the person has a case help them get the sale reversed and move on. If they don’t, they usually realize pretty quickly they are throwing good money after bad.

I’ve never had an issue with a vacant home, so focusing on those could help.
