There are at least two reasons why that's impossible to answer.
First, 2000 is a long, long, long time ago. It's not just property values that change. Communities change. People's tastes change. Where I am (Northern Virginia), I could show you two houses that had appraised for around $250,000 back in 2000. Because of changes in communities, traffic patterns, job sources, housing styles and tastes, etc., one might be worth $450,000. Another could be worth $700,000.
Second, the purpose of the appraisal matters. Bluntly, houses are often appraised higher for refinancing than they are for purchasing. I've seen plenty of homeowners who had their homes appraised for refinancing in 2005 and 2006 who can't believe how little their homes are worth today. The problem is: They weren't worth what they were appraised for in 2005 or 2006. Appraisals for purchases can be inflated, too, but that's somewhat less common and less extreme.
Have a Realtor do a CMA on the property to get a good idea of what that exact house is worth today.
Hope that helps.
