Once you have done your research and are going with your gut...
Not your neighbor's daughter, not the cheapest commission, not the agent that is a referral agent from 100 miles away, not the agent from USAA or NFCU because they are paying you a $1000.00 rebate that is out of that agent's commission. Go with the agent that is well versed and lives in your community! Also, it never ceases to amaze me how many sellers have never actually seen the listing the agent has entered in the MLS!
Please ask your agent to send the listing to you to review BEFORE they make it active. Why not allow YOU the homeowner check it out? Who knows your home better than you? Ask not, get not!
