Warm weather and April flowers is great for selling a home.  Historically, the number of homes for sale across the nation increases every April.   The sales of existing homes and construction spending were up in April.  The bidding wars are emerging on foreclosures as ready buyers work to take advantage of current market conditions.  Locally, April home sales were up a staggering 42% from the same time last year.  Mortgage rates are at an all-time low.  Buyers who have not owned a home in three years may be entitled to a tax credit of up to $8,000 if they purchase by November 30, 2009.  These market conditions are perfect for smart buyers.
