Taking over a rental, what are more options with lease?

[Jacob Wadlington]

I am purchasing a SFR home in Fort Worth, TX. There is a tenant already in place with a lease to the past owner for the next 8 months. The rent is below market value. Do I have the right to make the tenant sign a new lease with me and raise the rents to market value? Also, is it within my rights to ask the tenant to leave the property all together if I give the tenant 30 days to leave? Thanks in advance.
