Thanks Account Closed @Vikas Raoot, an opinion from an apartment building with the same problem:-adjust closer (in my building they are the commercial type) and the door is heavy and the frame on the outside is metal so that usually means a loud BANG. also may just need some machine oil....

.-  Monthly Expenses:  taxes: $125, water/sewer: $150, garbage $50, insurance: $125, repairs 5% (newer finishes, metal roof), vacancy 5-10% conservatively.-  I'd be looking at a conventional loan (possibly owner contract) with 25% down.  

@Michael Dang I used to work with MBCI in Houston on metal roof and panels for my projects, but it's been a while.

Does anyone know a good metal roofer with reasonable prices in San Antonio?  

Metal buildings, residential or commercial.

Many of the cheap screens sold in big box stores are plastic, higher end metal ones can be found. 

If you have the money, i would do that plus add a metal z channel going opposite direction of the joists ( screwed on top of the existing plaster ) and then add another layer of drywall. the Z channel leaves a space that helps in sound transmission. the problem is the sound is transmitted through the existing floor joists too, so just the insulation will not do it because the joists are still against the ceiling. this is something similar, but in this picture they used clips in combination to hold off hat channel from the existing ceiling which will lower your ceiling about another inch. 

While I was there, I met, all around good dude, @Marquis Harris  who told me about Bigger Pockets.

Thankfully the fire was on a Sunday and no one was hurt and the tenant properties were mostly unscathed thanks to the commercial property having a metal ceiling above the drop ceiling.
