But what's difference between "B" and "C"?

For a basement I would expect to find steel beams under those points running transverse to the home and bearing on the exterior foundation walls. 

Now Evil Cousin sees a nice house at Location B and applies to list it.

Thanks @Ryan Steele, I appreciate the welcome note.

Keep in mind your business plan, if your selling this in 2-4yrs your better off going with the cheaper sheet option-stainless steel or black depending on what that market likes-you can either buy and rent washer/dryers to residents OR try to get a laundry company in and do split profit.

Welcome, @Garett B. and @Yoko O. !

They don't get washer hoses hooked up correctly and they leak; dryer hoses end up smashed and not banded and blowing lint everywhere.

I  invest a lot into the rehab - new floors, new windows new kitchen  with stainless steels appliances- new bath,  full rehab. 

They were of course able to provide rent expectations (which for the most part I can determine myself), but the real value comes in knowing expected vacancy/maintenance/etc. on these B- and C class properties.
