If you give an inch thinking they will repay you for it they will just take a mile.

Would a 3 inch horizontal crack in sheet rock be anything to worry about?

Working with property managers, you can have access to a lot more than just 1 unit; however, they have their own system in place and as a tenant you ultimately need to respect their system.For example, you can't just throw in your own smart locks, hire a vendor to clean the carpet, or your own enhancements, etc.

I got my survey back yesterday and the neighbors deck is .4 feet or about 5 inches over the line on my side.

Another option for the ceiling is drywall over it or skim coat it.... if it's those square cardboard looking tiles then just sheet rock over it with 1/4 inch drywall.

One of my single family in Euclid had a problem with raw sewage during heavy rains mixing with the rain water and filling the basement with over 12 inches of that disgusting stuff. 

water and food shortages, public transport etc etc etc....have some compassion and make some temporary concessions on being a strong businessman and landlord.I would basically give them a one time "get out of jail free" card for late payment.... make it perfectly 1000% clear that this is a one time deal due to extreme circumstances...don't try and push it or there will be an eviction started.If they have been a good tenant and have had the respect to give you the "heads up" that they were going to have an issue paying on time, that counts for something with me....I know this is business and when you give an inch, tenants will often continue to push the envelope and take a mile...if they see you are "soft" they will exploit it.....but this is an extraordinary situation that just doesn't fit the rules.......

, unless you build your breakfast bar up above the stove a few inches.

The wall in the back of the first floor jutted out and needed to have the pipes moved so I could regain 6 inches.I know 6 inches doesn't seem like much but let me remind you the above ground square footage is 469 sq ft, every inch counts.I was impressed. 

Now, your soil profile will not change that dramatically over your life time... and if a couple of inches of topsoil washes away, it will not affect the pile.
