Thinking about buying both halves of a duplex seperatly. What are the cons?

[Rick Jones]

So i've been looking to buy a multi-family property in my town. I've recently come across a duplex that both halves of are for sale. One is a lender approved short sale and the other is priced relatively low also, i think to compete with the short sale price. The sum of the price of both of these properties is less than that of other multi-family properties in the neighborhood. Running the numbers it looks like it could cash flow pretty well. What would be the cons as far as buying both of these properties separately? I would be paying cash for both, would i be able to refinance them into one mortgage? Thank you guys for your help!
