Trends are often the result of media attention and usually have no value for your particular situation.
If you are looking to buy, my advice to you, as I have advised all my clients is get yourself prequalified, find the home you want to buy, the range you can really afford and have an agent make an offer to begin a negotiation.
If you want to sell, take the amount you owe, add the costs of closing you will pay (use 1% for a ballpark) add 3% for the possible buyers agent. Multiply your monthly payment times the number of months you are willing to wait for an offer, now you have your bottom-line price if you don't use an agent. An agent will provide the exposure that can shorten the time on the market...or getting you offers because your home is properly packaged...
Short answer: trends are not the key to a transaction. Finding the right buyer or the perfect home is.
