My clients receive the best sale to list price ratios--better than their competition because we study the market and work the market we're in. If you want the help, I'm an email away.
Be carefull with the largets investment you will ever make, dont let it become the largest loss you will ever have!
How could you list your home without knowing what your net proceeds would be? One of the first things a Realtor would do is determine your net proceeds and make sure you are okay with it. After reading your posts, I do not want to sound cold, but the questions that you are asking cannot be answered by someone that does not know
1. Your home
2. Your market
3. Your situation
We'd like to help, however the real danger is reading an answer posted here, then acting on it, and finding out later that it was the right answer, but to the wrong question.
