There should not be any conflict in interest if both Realtors work for the same brokerage house. I know I represent a lot of buyers who end up looking at and putting in offers on homes that are represented by my firm. It has never been an issue. The listing agent is representing the seller and your Realtor shoud be representing your best interests. As long as they are a reputable firm and you feel you are getting the best representation possible I would stay wiht the Realtor you have.
In regards to your other question about the price fo the home you have on the market. It si a buyer's market right now. The fact you received an offer is encouraging. A lot of buyers are taking a "shot" by offering a low number to see how motivated you are to sell your home. I would have your Realtor do an anyalsis as to the current market conditions. I do one every thirty days for my clients, See, if your home still falls in line with comparable homes. i do not knwo how loarge the city is, but here in Charlotte different areas of the city comand differetn price structures. Ideally you would like to see what homes in your neighborhood are on the market for and what sold recently in your neighborhood. If you cannot get at least three comparables then branch to your school districts and see what comes up. Some people are looking for homes specifically becasue of the schools. but thsi will give you an idea if their offer is low or on target for what the market is currently bearing.
last, do nto be insulted by any offer. I would and always do, recommend a counter offer. Even if it is small it will allow you to see how motivated they are to buy your home. if they come up substantially then you know they were taking a shot to see how motivated you were. if they are moving up incrementally then you have to decide what your bottom line is and counter in a way to leave you room.... more
