If it was listed by owner and not in a realtor's data base system (MLS), then only the owner will know the true number.
And yes, some agents are OK with providing you with information now when you are "just looking" recognizing that you are researching the market now and may not be ready to do anything for some time. Our hope is that when you are ready to do something, you will remember those of us who are helpful and will seek us out to help you then. I have people in my system who have been researching the market for 2-3 years while they are waiting for someone to graduate, get married, for a promotion to happen, etc. At the point that their particular "life event" happens, they will have researched the market, know what they want and where to find it, have a fairly good idea of the current price point for what they want (and in many cases we will have already visited the area and looked at the floorplans and neighborhoods to validate what they have seen on line so that they will know the great deal when it pops up and when they are ready to make their move). I've had others who I've helped who have never come back to me for anything. So please don't think that if you ask a realtor for assistance you are making a long term commitment to that realtor or locking yourself in with that realtor forever. You can find out a lot about a Realtor by how they respond to helping you wtih getting answers to minor questions like the number of days on market for a listing that's not their own when they aren't sure if they will be keeping your business or not after they answer the question.
A real estate agent can do a history report for you which will tell you how many days it has currently been on the market, price reductions that the sellers have made, and if it was previously on the market.
My office is located in St Peters and I would be happy to email that information to you. You can contact me at http://LetsGetItSold.com or firstname.lastname@example.org
Your REALTOR can give you that information and can compare other properties in which you are interested at the same time. Hope you're working with a good one.
