Thanks for the compliment Elizabeth. We have no idea what the market might be like next spring. So, you need to start preparing now. Here's what I would recommend as a plan of action:

1) Have someone give you an assessment of what you need to do to get your home in "show" condition.
2) Arrange for repairs of any known maintenance issues (such as wood rot, broken screens, etc.).
3) Have heating and air serviced if you haven't had it done in the last 6-12 months.
4) Implement recommendations from 1) above that you can afford to do.
5) Start packing ALL unnecessary household and personal items and put in temporary storage. The idea here is to open everything up to make the home look more spacious.
6) Have someone (an agent) do an immediate market analysis to determine approximate value and time it is taking to sell a home like yours in your area.

Also, see these articles on Property Presntation.

The question as to when you should put it on the market is a tough one. I would say NLT the 1st of the year. If you can be flexible with moving out before the transfer takes place, then list as soon as you have the first 6 items completed.

PS: Send me your address via email (don't post it here) and I will do a quick market analysis for you.

I currently reside in Loudoun County in a TH. I am looking at a job transfer April-May of 2007. Should I list now, or do you think it is better to list next spring?

Your website is so full of information. Thank you so much and keep up the good work!!
