Thanks to both of you guys.I'm planning this sale as a cash deal, so no real estate agents and the buyer has several other duplexes in the Peoria area (3 of them within two blocks of this house).

A block away from the Cleveland clinic.

So, whatever it is... eat the same meal, listen to the same song, wear the same color, etc.

Doesn't sound like it will be a particularly hard model to copy, and when the word gets out you could find 10 houses on the same block under cutting your prices by 50% or more. 

But 1) I bet you $100 every one of their neighbors has their ac set below 80. 2) when it’s 115 degrees out I guarantee everyone on my block has their ac set below 80, pry below 75. 

(We knew the parents so my wife just about adopted these sheltered girls).The OTHER girl's BMW would not start & it was blocking her vehicle against the 2 car garage & she has to get to her Gross Anatomy final (Yep final year pre-med).The wife went over (2 miles away) opened the garage door (no-one ever parked in as they had already lost the remotes) and she was able to drive into the garage & back it out.Same girls called the wife @ 11pm for baking soda to make cookies.

I have had mostly great guests, but the few that I've had that were terribly messy (much of what you describe but also smearing pizza toppings on the floor, having an easter egg hunt (I found some of the eggs) with chocolate in fabric and pink maybe egg coloring staining two sets of sheets) and yet were given 5 star reviews from prior hosts.  

If nothing else it's an education and starting block for your journey. 

I thought a block window with a shower insert going right up to it but maybe that’s more expensive and more work than I should be doing.

Vibrant colors, wallpaper, etc.
