For instance, if you have a basement for the furnace, ground space for the condensing unit, and it's a studio apartment...then that greatly simplifies installation.

My condensation of the prior discussions would be that you have to get out and look at as many houses as you can in the area, get as much data as you can, and develop a feel for values.There are multiple ways to fund rehabs.

Long story, but I'll try to condense it as much as possible!  

The other target is your condenser unit whether its caged or not..

Great shape but I saw condensation through the double pane windows.

This would cover a new roof, A/C condenser, water heater, refrigerator other mechanical items excluding a furnace.

IE condenser  all your copper etc.. .. with vacant houses if your getting squatters this is a common occurrence.. they rip anything out they can to pawn or take to metal recycler or sell your stolen condenser on craigs list.. .. 

you should work on condensing your message.

Matt-Make sure you get the AC Condenser protected!!

I would agree with everything that John said in the previous post, I have clients looking to rent by the Lake, (neighborhoods like Lake View and Edgewater)  then  busy and condensed areas with a lot of things to do (like Boystown, Bucktown,  South Loop,  Andersonville) and also areas which are close to universities are always hot for tenants (Loyola Rogers Park / Northwestern Evanston, Hyde Park, Little Italy, Southport Corridor/ Lincoln Park)
