I think I have hit on a decent business that could employ 1 or two people and still generate a very reasonable return.My thoughts are the renter's would sign a loss and liability wavier and I would provide security cameras and lighting.

My goal is to own 600 units by 2030 by using the BRRRR method.

I learned the hard way.https://www.pabulletin.com/secure/data/vol28/28-44...

@Caleb - which method do you prefer after doing both?

You will have little wear and tear on your properties, they will be living on Social Security and your rent will be the first thing they pay you!!

So I've obtained July and August rent in advance, and secured a larger deposit than normal. 

So I am in the process of finishing up a rehab i have been working on for several months now. I wanted to do a BRRRR strategy but have been thinking maybe its not to smart for me to holding on to property without cash...

I was told by the manager that HOA cannot do anything about it, but I know for sure that the air duct can be insolated and properly secured to minimize the noise and avoid wall vibrations.

But that shouldn't really affect your ultimate returns in any meaningful manner even if you use IRR method.  

I would definitely not refund June, and would treat security deposit as normal (use for actual damages).
