Recommend have it authored in special provisions for the contract if NO appliances are present on property.
IF you are searching for BRAND NEW appliances more than likely your offered could be declined. Most of these homes are purchased "AS IS" .

If you are getting a loan it will likely be required by your lender that it have a stove/oven or cooktop/oven. In my experience they will typically add this before closing if it is a lender requirement. I've also seen microwaves and dishwashers replaced. You can't count on this or guarantee this.
I have personally never seen them add a fridge or washer/dryer.
With Freddie/Fannie properties I think your realtor is correct. You pretty much have to get the bid first. Then try to negotiate repairs. If the appliances are a deal killer for you, don't bid. You may not get them and you are more or less locked in on the contract. It is not like buying a home from an individual seller with more opportunities to back out of the contract. So you have to think of it more of a bonus, if you get them great BONUS....if you don't you bid appropriately in the beginning and aren't disappointed if you don't get them.
