Combining 2 sales into a single escrow?

[Rob Saunders]

So the buyer of my 2 duplexes (side by side properties) has asked for a single escrow to save a few bucks. I am looking to do a partial 1031 exchange; around 50% of the total proceeds but not clear as to whether the single escrow affects this. Each duplex has a different sale price,  amount of debt and profit. Any information on how best to do this would be greatly appreciated.
