(Noise issues)So screening is the key, but in your case, where he has to move in quickly, that's a red flag, IMHO.

Do you think 3 days is too aggressive for a noise issue? 

Other repairs since the new tenants moved in include, a sliding door lock replacement, drywall repair from a roof leak, 4 cracked windows, a broken front door handle, light fixture replacement, blinds that are longer than the window, window screens and now a ceiling fan making grinding noises. we're about $5000 into repairs/replacements right now since the tenants moved in.

I am concerned about damage and noise of course thank you.

There's already a lot of noise/options/competitors in the space - each promising what you mentioned, and then some. 

It's tough practicing in my current condo due to worrying about noise bothering the neighbors...  

She has complained that the AC was, making funny noises (it was fine), that there is an issue with the metal roof (there isn't), that she thinks she has carpenter ants (not likely) and just generally annoyance.Has anyone had an issue with a tenant who always seem to have, often imaginary, issues? 

I’m nervous that it will be tough to retain future tenants due to the noise issue.

Guests provide reviews that noise transmission is high and privacy is low. 

For example if there is  noise or on street parking that is prohibited they should complain to the police.
