How much notice to give tenant you’re selling in texas

[Steve S.]

I have a tenant whose lease expires in May. Located in Texas. Planning to sell the property. Will give them plenty of heads up. 

I understand the lease has to be honored which is right to do anyway. 

Is there a set legal Amount of time one must give the tenant?  

Obviously they need to know as well given people will be coming to look at alit and, maybe the tenant wants to buy the place.

Quote from @David Krulac:

In Pa.  selling a rental property does NOT terminate the lease.  The new owner is still bound by the old lease.  If I'm selling a property, I give the tenant long written notice.  For example for leases expiring June 30, I have already given notice in January. In today's tight rental market and higher rents, your tenants may have a difficult time finding a replacement rental.

That's true in every state. Existing contracts transfer with the sale of the property.
