When you come to a site mostly populated by people that make a living assisting people buying and selling houses, what type of answer do you expect to your question? You'll get a lot of answers probably containing "Crystal Ball" which makes me think there is a NAR class somewhere that mentions if someone cites data predicting future trends, break out the crystal ball analogy to make them seem ridiculous. Maybe next year it will be tarot cards.
Anyway... as for the fed funds rate, the rhetoric from the fed and the markets are betting on no change in the june meeting and a 1/4 pt raise in rates in the august meeting. But the fed funds rate change does not mean a direct change in mortgage rates. The two are highly correlated, as the fed funds rate affect short term yields which affects 10-year yields which is what mortgage rates are tied to. But in the past year and change, the fed funds rates has been cut from 5.25% to 2%, during that time, mortgage rates have actually increased. Right now the spread between the 10 year treasury yield and mortgage rates is the highest its ever been. So an increase in rates only means the fed is now trying to hold off inflation and when banks get a better handle on who is credit worthy and who is not, the spread between the 10-year treasury yield and mortgage rates will close. All this means that regardless of what the fed does, its likely that rates stay about where they are for a while. Right now, in most of the country, home prices are still falling and inventory is increasing. So even if rates go up some, if the price falls, you'll do fine, and you can always refinance rates, you can never change your purchase price.
