It'd be kind of a long run, and you might need to check how long of a vent run the fan can take, but it might be an option.Broan makes some fans that are thin enough to mount in a wall that has 2x4 studs. 

The service data sheet that came with the 10-year-old Hotpoint (GE) 18-cubic-foot top-mount no-frost in my house says that with the freezer knob at 5 (on a scale of 1 to 9) and the fresh-food knob (if equipped) at C, which is also the middle, you should have:70 F ambient: Fresh food 33-39 F, freezer -4 to +2 F, percent run time 26 to 36%90 F ambient: Fresh food 33-41 F, freezer -4 to +4 F, percent run time 40 to 56%The service data sheet that came with my 3-year-old Frigidaire (Electrolux) 18-cubic-foot top-mount no-frost at my rental says that with no load, the doors closed, and the controls set in the middle, you should have:65 F ambient: Fresh food 35-40 F, freezer +2 to +8 F, percent run time 25% to 35%90 F ambient: Fresh food 35-40 F, freezer 0 to +5 F, percent run time 45 to 55%Another rule of thumb I have heard is that if you have a box/tub of ice cream in the freezer, it should be soft enough that you can scoop it - not a solid block but not runny either.Like @Jennifer Rysdam and @Joe Splitrock said, cleaning the coils can help. 

The receptacle gets ground via its mounting strap being screwed to the box.

Frank Ross downtown Mount Pleasant has experience working with real estate investors and has owned a rental property himself I just started using him this last year but he has been super helpful and is okay with calling occasionally with questions without a cost (probably because I did my taxes there).  

@Brandon Sturgill thank you I live in Mount Vernon oh definitely interested in wholesaling

@Mike Reynolds what if you did the wall with 2x2's to save a couple inches and then did  a galvanized pipe rail mounted on top of the wall at whatever height the handrail needs to be (36"?)

I'm thinking to use Salsbury Recessed Mounted 4C Horizontal Mailbox - 10 Door High Unit (37 1/2 Inches) - Single Column - 1 MB3 Door / 1 PL5 - Front Loading - USPS Access.

Sadly, it’s like watching a train wreck in slow agonizing motion when a homeowner tries to mount a defense.  

You can buy a new wall-mounted bowl for under $300 and put it in yourselves.
