Advise Needed

[Amanda Brown]

My husband and I are looking into purchasing a home from a family friend to be used as a rental property. We have NO experience in real estate but would love to use this to get started. 

Our family friend loaned the occupant money and they put their house up for collateral. Needless to say the occupant did not follow the promissory note and has defaulted. 

Instead of going through the eviction process our family friend wants to sell the house to us for a low price ($15,000).

My question is, how much trouble would it be to evict the occupant after we purchase the house?

Thank you in advance!
