Metrowide, the $190k - $250k price point only has 8 months of supply.... the lowest figure for any price range right now! Given that New Brighton's average sales price is $250,000, I believe you are in a good position. New Brighton does have a great location and I think is underrated.
Whatever your home does sell for, in this market you're going to get a better savings on your move-up than you are "losing" on your sale... so I would be looking to price aggressively so that you can take advantage of the remaining sluggishness in this market on your buy side. Historically, sales are strongest in the March-July time frame, so you'd maybe see a slight improvement in the price of your current home but have less leverage on the purchase of your next home.
Also, rates are hovering near 6% today but were as high as 6.75% just last Summer. If they do trend higher, which I think they will, you'll see your buying power shrink slightly.
The sooner you list and the more aggressive you are with pricing, the more likely it is that you will be able to take best advantage of this market on the buy side.
