As the owner, you have the right to enter and to show the house to prospective buyers pursuant to Civil Code section 1954.
You are NOT obligated to agree to an early termination of the lease. If the tenants refuse to permit showing, you will probably need an eviction attorney to evict them after having served a 3 day notice to perform covenant or quit.

You have lots of negotiating room. Whoever buys the house will probably want the tenants out, and you probably are counting on selling it long before August. Although the tenants cannot prevent you from showing the house, you cannot abuse the privilege, and you still have to give notice. You may have an opportunity to prevent arguments down the road by coming to an agreement about how often you can show the house and what kind of notice that you or your agents have to give before doing so.
