The market is a moving target right now. I would not classify either Hoover or Helena as "good" markets. Most Over The Mountain areas are suffering from a disproportionate ratio of supply & demand. I do agree with the observation about the recent increase in available inventory. In the last 60 days Hoover's inventory has increased 25%, Helena/Pelham's 10% and overall MLS inventory 20%. A huge number of new listings have come on the market in the last 60 days with most of those in the last 30 days. This will do nothing but force prices down, not up, despite new construction increases. New construction is a different product from existing re-sales.
Homes are still selling in both these markets, albeit at lower numbers, but Helena/Pelham is performing better than Hoover in ratio of sales to listing inventory. Many factors would influence the decision of which property to sell this year. Without having specifics its hard to make a recommendation but in general, if you had to sell today, Helena would be the one.
I do not see a price increase coming anytime soon. For the last 24 months, in any model you look at including 3,6 or 12 months revolving sales, both Hoover and Helena/Pelham have seen a drop in the average sales price and they continue to drop through the first quarter this year. There will be no price increases until inventory levels match closer to demand levels. Here's hoping that happens soon because it will help us all.
