@Account Closed the comps tell you what another person was willing to pay for a similar property, not what you should pay. Only the buyer knows what numbers will work for them. If the numbers only work at a much lower purchase price, then that is what should be offered. Convincing the seller of that price may be difficult or impossible, but it worked for me on a number of occasions. This is especially true if the property or seller is distressed and just wants out.
@Christopher Giannino Comps may be good to look at initially, but there are so many variables that can change that price drastically. In my town, even going over the railroad tracks put you into an undesirable neighborhood and the prices drop. Something you can try, if you want to find properties that have sold, is using Zillow, type in your target area under the "Buy" section. Then under the "listing type" tab, select only "Recently Sold". You can also ask your agent to run some comps for you.
