You don’t have to stop doing that, but you may want to do things like learn about foreclosures and/or other things that may enable you to take advantage of distressed sellers.
You have to be careful with distressed foreclosure pending forced sales. California has law governing equity buying (below “market” purchase of a home facing foreclosure).
How much you know can play against you if you don’t put the right foreclosure equity disclosure and rescind agreements in your purchase offer allowing the seller to later sue you for perceived lost equity from your predatory actions.
I suspect we’ll see an increase of these lawsuits in the coming years.
