Ballpark estimate for this garage repair based on pic?

[Mike Warder]

I'm looking to acquire a buy and hold rental home that looks okay numbers wise if this garage repair isn't too outrageous. I've never dealt with siding/garages. Anyone care to give me a ballpark estimate/range? Supposedly, it was caused by a storm, but it is an REO property and the purchaser is on the hook for it. Sorry I don't have more details or a photo of the inside. All advice is welcome.
