Thanks Tanner, I’m mostly interested in learning about construction so that when I view homes I have a general idea as to how much an imperfection, like a torn carpet, might cost.

Carpeted areas will probably need removed down through the first layer of subfloor.

I was able to terminate the lease early, she wouldn't pay for repairs to the house (carpet stains/cleaning, a broken floor tile etc) and gets off the utilities, but paid a termination fee equivalent to the leftover rent.

we have changed out the carpet and paint as the tenant moved out, replaced the roof, and built a fence in the back What was the outcome?

We charge a pet fee for visiting pets that is at the high end of boarding cost and at move out we charge to have HVAC professionally cleaned and carpets professionally cleaned (many of our units do not have any carpet) to place unit back in animal free state (many people are allergic to pet dander).

Carpet is a no go.

Like, they didn't clean the home or change their bed sheets for months type of mess. I

You might want to think about pulling up the carpet and taking a look. (2) Maybe the water delivery piping under the floor, hot or cold, has developed a pinhole leak and is spraying onto the subfloor from below. 

We are now closing in on a year since the original purchase, and the thing is still a mess... I

I have kinda been against installing carpet but it might be an easier and cheaper alternative.I would love any and all thoughts.
