Storage only, if it does not have a egress window. 

Yuck.I do not want window units since this is a higher end home.

So I crawled though the window.  

Sorry, I had this in the wrong discussion category.I am a spec home builder, and we don't use window coverings in the houses we sell.

A lot of the housing stock, in and around Baltimore, is fairly old (1940's and 50's) and typically requires a minimum amount of rehab that often include: rewiring, replumb, roof, windows, kitchens, baths, cosmetics, and oftentimes a full gut to the studs.

However, there is definitely perceived value in a property with new appliances & new windows.  

Thank goodness it was summer so we could keep the door shut and window open for a few days.

And for further confirming the unlikelihood that rental income increase would play much of a factor if at all.I'm trying to fast track the subdivision inquiries as much as I can during our contingency window because that's the only scenario where this property will make sense for us.  

Wall R-13, window upgrade takes you from what?

I can't count how many apartments I've gone through where tenants "repainted" all over the trim and windows, making the unit turnover repaint take twice as long and cost twice as much.
