Hi @Akyl-Lateef Hewitt, You can Google topics like choosing a safe, sound and reliable Qualified Intermediary. 

@Jeremy Flores house hack is your best bet.

Please tell me what you have done from your past experience to safely make this happen.

investors that just got in the game post 2009  were spoiled in thinking that everything had to cash flow with minimum down and cash flow positive a lot.. when in reality in a strong market with good demand safe secure properties  minimum down break even is a great out come and many times a little bit negative while you wait for rents to inch up. .you make your money in appreciation and tax write offs and your tenant paying your mortgage for you.. 

As others have said carpet is certainly your best bet, if with the under lament and quiet rock on the ceiling about the sound will travel. 

Mobile Home owe 43k safe value 100k (plus 300 month currently) 8.8%2.

Plus keep in mind, if this is your first time out, they will want to cover their bet on you.

Your phone is likely your best bet. 

However, the ground-floor tenant has been doing some reading and has come to the conclusion that he doesn't feel safe having his family right above this equipment, so he turned off all the water heaters. 

Service them once a year to ensure they are clean, operational, and safe.
