In a normal situ, you will need to clean, repair and paint at least.
The house will sell quicker and sell for more it you do not have Tenants.
You cannot expect the tenants to cooperate fully, much less have the place clean and presentable too.
The is also the WOW factor; meaning that you only get a short time, after you LIST, to knock their socks off.
Have your Realtor do a good CMA and then price 10-15% lower to get multiple offers.
That will be good timing for the Back-to-school crowd too.
