Halfway through, the dark green/yellow gunk at top left is the glue that was holding the parquet in place.

Not a huge fan of this post it was once a time you didn't know what you know now and I'm sure you had plenty of questions... like many have said if it's an issue don't post stay in the dark a forum is for people who are looking for info

I just started and feeling my way through the dark, any help will be appreciated.

I have used Colors Unlimited as carpet installers for my rentals and they did right by me. 

The colors you choose and the flooring style is exactly what you would find in "the parade of homes" I love it!

Possibly using a professional third party vendor for the pre-inspection is a great idea, give a copy to the owner and tenant Excessive holes in walls Broken tiles or fixtures in the property Plumbing backups Repainting where a tenant has repainted from the original color Tears, holes, stains or burn marks in carpets Missing or damaged blinds Broken windows and window screens Broken doors and locks Broken or damaged appliances Excessively Dirty Pest control if you see Bugs and or fleasJunk or trash left behind Past Due rent Fees incurred from fines from the association due to the tenants conduct or lack thereof Water damage to hardwood floors Missing outlet covers Remotes for garage or gate if not returned Rekey of locks if tenants did not return the keys Unpaid utilities, as long as they were part of the lease agreement Undoing a tenant alteration This is a sample of things that are usually considered to be normal wear-and-tear and should not be deducted from a security deposit: Slab or plumbing leak Normal rug wear.

if you just have all the interiors sprayed one color then it will probably only take about a day for a pro

Hammond has always been a mix so it's not a shock to have neighbors of different colors.

I like to hang my shelves on a 1x3 that I paint the color of the wall. 

When they contacted me with the color they provided a color for every room.
