Sure if you are buying a condo downtown you can probably get away with using a discount broker. 

There are few realtor I talked to say, we charge this amount and said, I wont get a discount on houses we look at.

Of course, if you can buy at a steep discount, get favorable interest rates and put a lot more down, you can make almost anything cash flow.

Depending on how much material or items you need there's always people selling excess material and items they ended up not using or needing, typically at a discount.

The answer to your question will be found in your lease agreement and no one here has read it so any advice would not add tremendous value.

I would try to get him to take possession earlier for a discount so at least you have utilities and etc out of your name and some money coming in earlier even if he doesn't fully move in earlier.
