So instead of waiting for the problem to compound until the lease is over, the plan is to replace the carpet immediately rather than try to muck with cat urine and get it 80% clean with various other solutions.

Adding mass to the walls works wonders—attach Mass Loaded Vinyl (MLV) to the shared wall, then cover it with a layer of 5/8” drywall using Green Glue soundproofing compound for extra noise-blocking power.

Caveat is that you should be reinvesting those profits back into other smart investments so that you aren't missing out on compounding gains. 

I'm not sure if the contractors are trained to exacerbate every single problem or not.We recently discovered asbestos in the compound joint.

And the cracks mostly follow the drywall seams from what I can see, which is typical....And as @Patricia Steiner said, it doesn't look like a pro installation....You could ask the Contr to use a flexible compound if this happens again, or maybe even now...https://www.dap.com/products-projects/product-categories/pat...Like everyone else said, I'd have it repaired - by a licensed Drywall Contr. - and then just check in on it.

Tenant covenants and agrees to pay interest at the maximum lawful rate or eighteen percent (18%) interest, whichever is less, compounded annually, on all unpaid Rent, damages, and other amounts owed by Tenant, excluding late fees, from that date of Landlord’s final accounting until such time Tenant pays all such outstanding amounts.

My stock portfolio has compounded by 45% annually over the past several years and I routinely take profits and derisk, go into cash and then back if I find deals.

The difference between a 12% return and a 16% return compounded over 20 years will make you sick to your stomach. 

This allows us to 1031 exchange post-sale into a new deal, compounding cash-on-cash returns and deferring capital gains.Let me know if you’d like to discuss further!

As a would be individual landlord with just a one unit single family property I don’t know I can stomach the risk or withstand a financial assault resulting from an eviction process for a non-paying tenant (or tenants that do extensive damage).I am seriously considering bowing out and selling.
