I think the question beneath your question is, "What if every expense on my rental properties doesn't have a direct ROI?"

The hardwoods beneath the carpet appear dark at spots, which leads me to believe urine soaked through.Any tips?

You need to scratch beneath the surface before you speak to/about strangers in the way that you do.Account Closed noted.

The image you are seeing is the ceiling beneath the drop ceiling on the first floor and the blackened wood is where water was dripping from the second floor.

@Marc Desrosiers That's a great idea about using a double hanger and adding blocking to make a shim.

At this point we will have to remove the floating engineered wood floors, rip out the flooring beneath (suspect original wood floors), seal, then put in a new layer, then reinstall the wood floors after sealing the bottom of each plank, then seal the lower part of the walls, then repaint.

This will probably require insulation beneath the existing subfloor, so you could tackle that job first, then proceed to fix the subfloor squeaks afterward.If you want to avoid doing these as DIY projects, your best bet would be to try and find a flooring contractor, or perhaps even a handyman, who would be willing to fix this problem.

This is simply to allow for an emergency situation such as a rotted sill beneath an exterior door.

So I believe in turning over leaves and seeing what's beneath them but am having ZERO luck getting any realtor to call me back!!
