Gutted the floors myself and installed new subfloor and new flooring on entire first floor.

I'll go with @Greg Scott line set metal cover idea and @Chris Seveney idea for painting the copper white.Thanks folks!  

They sealed the entrances using metal screens (one around a pipe), but now the areas look unsightly.Additionally, there’s ongoing construction in the condo complex, which may have driven the mice into my unit.

Install cameras and exterior lighting on timers, place no trespassing signs, and place items that indicate occupancy - like a BIG dog bowl near the front door, shoes, etc. 

You don't have to buy one, you can install an app on your phone that will accomplish the same thing.

I know they are compensated per unit for the inspection, do you think it would be an issue if I just registered a fifth unit and made sure it met all the requirements?

The big stuff left is refinish floors($1050) and install doors/trim and molding.  

We tried having the smallest washer/dryer installed, but the install team couldn't make it work.

Tailor these amounts to the significance of the task; for example:Roofer: $1,000/day (critical to weatherproof the site).Painter or garage door installer: $100–$200/day.Contract Value & Payment Terms:Agreed payment amount (lump sum or itemized costs).Breakdown of payment terms:Deposits.Progress draws.Retainage (if applicable).Scope of Work:Be as detailed as possible.

How many are you installing a year?
