If you're a home owner considering selling, yes, you should worry a little bit. Not tremendously, but don't put your head in the sand and say 'What, Me Worry?' Be educated, cautious, and careful.
The market is making yet another correction. Be aware of it. Make sure you are looking at the latest comparable sales when pricing your home for sale. Pay extra special attention to your current competition. That competitions number of days on market and price reductions in your neighborhood.
Something that should always be brought to a sellers attention, well until the first 1/2 of this year where a seller could toss it on the market and get multiple offers and all cash investor offers too!
Investors are finally disappearing from the market. Good for buyers, not as plentiful of offers for sellers.
Don't lose sleep over it, but don't be stupid with your list price.
