Purchasing a Portfolio of homes?

[Brian Lipszyc]

I've come across a possible deal to purchase a few rentals, currently being "packaged" as a single portfolio.  Together, the numbers play out very good, but I'm not sure if purchasing it as a complete portfolio is the right thing to do?  Is this done often?  How would I eventually cash out down the road - do I refi each house separately?  Open to suggestions on what to read/research to possibly make a move on this one.
