Get an independent appraisal for the value of your property. Realtors often overprice a property to get you to sign, then tell you a few weeks later you have to drop the price to get a sale. I got burned by a realtor overpricing my house, then showing houses a couple of streets away, virtually identical, with lower, more realistic prices. Of course the buyers went for the "deals" instead of mine.
If you get a professional appraisal for $X, and the house sells for less, you can probably take a tax credit for the "loss", legally.
Definitely use an attorney! Well worth the cost!
It's a stressful experience no matter what, so be prepared and maintain a sense of humor. Moving sucks, too, our last move damn near killed me with stress and bad movers.
Best of luck to you, and keep your eye on your goal to give you some focus.
+1 on the appraisal.
Tax credit for the loss on your residence? No way. Nor can you deduct the loss. See IRS pub 523. Download a copy so you know the tax implications and consequences of selling and buying.
An attorney can be a never ending money sucking hole. Things to watch out for when FSBO:
Buyer insists on using a contract drawn up by his attorney. The attorney naturally slants the contract in all manner of ways in order to protect his client. You will either have to negotiate it yourself or pay your lawyer to do it for you. Figure $200 an hour or more. Your lawyer better be a real estate attorney too, or you
will get screwed. Even if he is a real estate attorney, you might still get screwed.
Buyer's lawyer wants you to sign lots of disclosures that aren't required by law. Bend over first if you do.
Your lawyer has to travel to the courthouse, settlement location, or elsewhere on your behalf. That will be at his billable rate plus expenses, both ways. Get a local real estate attorney. The closer his office is to the courthouse, the better.
Buyer's lawyer (or worse, your lawyer) wants to negotiate the deal lawyer to lawyer, all at the billable rate, of course. Some lawyers bill brief phone calls at 25% of the hourly billable rate. A few calls can run up quite a bill.
Buyer's lawyer owns the title company and/or escrow/closing agency. Expect paperwork you know nothing about to be put in front of you at closing time. You will either have to walk or sign it without legal advice. If the buyer's lawyer owns the escrow agency, the buyer will effectively control the earnest money.
I have run into every one of these situations. Fortunately, I know how to read a contract and have been able to negotiate the deal without my lawyer being involved. Only when everything is negotiated and the buyer has signed do I run it by my attorney. So far, I have come out smelling like a rose, because I insisted on doing it my way. And I have walked out of a closing because they tried to pull a last minute stunt.
I suggest you interview at least two more agents. The standard recommendation is to interview three. There are more than a few bad agents out there.
Oh, lastly, as an example of a really stupid thing to do, someone I know once hired a real estate attorney who was located 90 miles away, because he was an important and powerful lawyer in the big city. The travel bills alone were staggering.
