Need Advice Window Treatments in Rental House

[Kristin Kiddy]

Hi everyone.  I am a new"ish" landlord and I need window treatment advice.  In my previous property I installed blinds/shades in all the windows.  It was a wood frame house with normal sized windows so I could install the cut to size blinds from Lowes/Homedepot and being wood, I could patch any holes very easily.  

Now I have a new property here in Florida and it is a concrete block house with some big windows in the living room.  I am NOT going to buy custom blinds for this house so my two options are 1. install three standard sized blinds in the window to fill the window space OR 2. install a long heavy duty curtain rod and either put up some neutral (cheap) curtains or allow the renter to put up their own curtains.  The walls are block and very difficult to install anything property so I don't want the renters trying to put up anything themselves.  I would love your opinions and expertise on this one...  Thanks!
