Keep grinding 

Some have something to say no matter what the question is.You always have to sort through all the noise.

Parties and noise that makes my neighbors unhappy.  5.

And yes east CM has airport noise, and is close to the price of Newport Beach back bay, but it's NOT Newport beach.

I have a no pets policy for my rental, a one bedroom apartment that is an ADU on the bottom floor of a larger house that is a separate rental above, because there is less insulation between the walls, and the noise carries and barking could disrupt the other tenants.

We don't plan on selling the house anytime soon, and can be patient while the process slowly grinds along.

If you have an old creaky uneven floor with no insulation, it makes pretty much zero difference what you put on it - carpet and padding may be best at that point if noise dampening is your biggest concern.
