Pricing strategies vary based on the type of sale, property location, property condition and motivation of the seller.
Some sellers will overprice; some price just right and some will....under price.
In my opinion to "under price" can be a good tactic.
Key point: Sellers must understand that to price a bit under the market or at the low end of the market is not the same as "under sell."
No seller can be compelled to accept any offer. There is absolutely nothing wrong with pricing low and getting multiple offers!
