Hi Ruby and thanks for your question.
And you're astute in recognizing that two homes for sale might have a negative effect on your home.
Competition is usally a good thing in buying products, but, for the most part, competition amongst products tends to drive prices down, not lift prices up. So, in my mind, I would suggest waiting--especially now. Depending on the location, type of home and price of your home, buyers may not be as plentiful as needed to support two home sales side-by-side and on the same block. My suggestion is that if your neighbor already has his home on the market, you might wait just a bit (preferably long enough to allow the home next door to sell) before listing your home.
In waiting, you'll be able to gauge the market, see how many buyers show interest in the home, and also, to determine the consumer's perceived "pricing" of the home.
Had this been another time of the year or diferent market indicators aplay, I might give you a different answer. But if you're talking about right now...I'd wait for just a bit before listing and selling the home.
Most importantly, use this time to find a great Realtor to help you! And, no, you do not need to use the same Realtor as your neighbor. Aside from familiarity with the community, your neighbor's realtor will not offer a "quantity" discount on the listing and may not be able to provide you with much information about your neighbors sale. It's best to find the one Realtor to work with you and with whom you feel comfortable in his/her skills.
