Your Realtor is not a mind reader so keep the chat line open. If you feel he or she is not showing you homes you have an interest in go back to your list & clarify early on.
If you really like a home but your Realtor has given you an important piece of information that may detract from your decision give it careful examination.
Always keep in mind the home you buy appealed to you for a reason. Before you buy think of re-selling this home. Would the next Buyer see an appealing property? When you look at it in this light it should help your decision.
