How difficult would it be to evict a squatter from a house?

[Brandon P.]

There is a property for sale that I like, I think it can make a good rental. The owner warned me it may be squatter occupied, and I went to look at it myself, it bad clothes hanging and 2 locked doors that I assume someone was living in. The owner seems unwilling to evict the squatter, but is willing to lower the price. If I purchased the property how long, and difficult would it likely be for me to evict the squatter? Property is in Mississippi
