I am attending college here in Columbus Ohio USA working on my Master's degree in Nursing (MSN)?

I am going to school fulltime and working part-time.I inherited money from my deceased father and was wondering whether to use $220,000 dollars to buy a 2 bedroom 1250 square feet condo or keep it invested in Abbott Laboratories stock??? I currently rent $675/month but my building is being sold and I'm sure they will raise the rent.Would i do better by keeping it invested or buying a place with no mortgage payment.
