In this economy I can see that people are having a hard time deciding whether to "spend" money on staging. The better question is should you "invest" in staging. Staging is an investment, and an investment that pays you back. According to the most current stats from Stagehomes.com 95.6% of staged homes sell on average in 37 days or less. The non-staged homes averaged 212 days on the market.
What is the typical price to stage a house? That varies widely, depending on whether it is vacant or occupied. If it is an occupied home you can get a staging report for around $150 -$250 that will tell you exactly what you need to do to stage the home yourself. The next step would be having a stager come in and do the actual staging which may range from $250 - $700. On a vacant house the price is higher, but generally $1,000 - $3,000 is a ballpark range.
Prices vary by stager, area and the situation but I think you can see that staging generally costs less than a monthly mortgage payment. Now how many payments are you saving if your house sells in the first month?
Oh, and if your house is sitting on the market for over 3 weeks, what is the first thing your Realtor is going to recommend? A price reduction! With most price reductions starting at $10,000 or more, doesn't it make sense to stage your home in the beginning?
