Trouble selling condo in Houston TX. Any advice appreciated.

Hi everyone, my friend has this condo in Houston, TX that he's trying to sell since the begining of this year but the property is still on market. It's in great location, just about 8 or 9 mins to Rice University and medical centers. I thought since it's in great location, it shouldn't be that hard to sell but it seems I was wrong. My friend already moved out of town and really wants to get this place sold. I'm not familiar with the market in Houston and would appreciate any advice or recommendation.
