You could call them to try to make friends but you're probably not going to get the property at a discount. They are fellow investors, not distressed property owners. You need to look for an ad with words like "Needs work, value in the land, must sell quick".
@Geordy Rostad what if they are employees?
If you are looking at single family homes and see LLC's that own them, it's probably just small companies or individual investors using LLCs as protection. In most states you can look up who owns an LLC.
