Pay off Student Debt or Invest

[Nick S.]

I am 24 years old, just graduated, and I recently settled in personal injury lawsuit and will be walking away with around $20,000 in my pocket.  I currently have $10,000 on a lease on a car. The lease is still going for another 27 months. I also have a high interest $5000 student loan and no credit card debt. I am currently renting out a room in a house with my girlfriend for $475 a month plus $125 in utilities. I was just pre-approved for a house up to $175,000 on my income alone and currently reside in the Milwaukee area. 

I am looking for recommendations as to what I should use the money for. I would like to purchase a home and use an extra room for extra income but I don't know if that is the best use of the money. Any thoughts?
