The tree can be removed but even if they grind the stump it may not be completely gone.

Creaky wood floors make more noise than carpeted floors.

We ended up pulling up the LVP, pouring SLU in the worst low area, and grinding down minor high points and filling minor lows with a skim coat, but not doing the plywood underlayment.

It's gonna be a grind; it's gonna take some money.

Also watch out for HOA restrictions that may prohibit certain kinds of establishments, noise, hours of operations, and odors. 

There is a bunch of noise in the data and not due to PS but the data sources have the noise. 

I own a rowhouse in Baltimore that I'm renting out and my neighbor's roof has a hole in it - a racoon is going through that hole and into the attic space above my tenants' bedrooms and making noise, which the tenant is complaining about. 

Okay, now reading over your lease agreement as I noted earlier and as you mentioned, it could be better but, there is one clause 'Noise/Waste' that could apply here, is the Tenant creating a nuiscance?

Keep grinding and you will get there!

The problem I think I have is after do repairs and buy a couple of multifamily complexes will that grind me to a halt once all of that equity is gone - or am I missing something here?
