Those IntermediateOutputPath's can be inserted when MSBuild is given a bad path.

What did work:

$(SolutionDir)out\bin
$(SolutionDir)out\obj

To help troubleshoot your particular case, try turning on diagnostic MSBuild output and logging under Tools->Options->Projects and Solutions->Build and Run-> MSBuild project build output verbosity. Then, search for the generated folder (ex. "Temp").

Using common proj/props/targets file is a great idea, but it does require fighting Visual Studio a little.
