April data shows a tighter Greater Toronto Area real estate market with a 7% year-over-year sales increase and a 9.3% drop in new listings. The sales-to-active-listings ratio indicates increased market tightness compared to last year. Overbidding rose to 13% of neighborhoods, while 84% saw underbidding. Despite a 4.9% decline in average home prices to $1,051,969, prices are expected to rise as the market tightens.
