That's it, but a) print out a page for each property you think is comparable, b) make the list of repairs long and inclusive of everything you've done. c) Put larger items first like kitchen remodel......and don't just say 'kitchen remodel', list things like 'custom backsplash tile/Bosch appliances/recessed can lighting/pot filler/etc. d) Cite the price/value of the work done, and don't be afraid to be generous.

People who are successful versus failed with OOS tend to follow certain patterns.

Along the way, I discovered hardwood floors under the tile (unfortunately, not salvageable) and replaced them with new hardwood.
