Comparable Sales and Your Offer Price
Gathering and analyzing information from comparable sales helps to establish the price range you should consider when making an offer to buy a home. More weight should be given to the most recent sales (in the last 3 to 6 months), but even so, you need to do a bit more analysis before setting upon the price you will offer.
You also need to consider the property condition, improvements, the current market and the circumstances behind the seller’s decision to sell.
When you have all this homework complete, then you can see the complete picture and make an offer based on all the available data.
