Lots of times they are not widely advertised as land deals are a highly relationship driven market segment.

Often I listen to Grant Card one Power Players segment where he interviews people that despite adversity " made it".

How much house selling experience do you have for a new market segment?

It's hard to stand out.There are some new owner-occupied segments with people who share motivating factors for selling their home.Seniors with Long-time Ownership: often ready to downsize or transition to assistance.Homeowners with Low Financial Stability Scores (FSS): Struggling financially and likely ready to cash in on their asset.Both these categories have additional advantages in that they probably don’t haven’t been updated and may have deferred maintenance.
