I work with a company that you should utilize to analyze the different properties you are looking at right now. 

There's a few different ways to focus on a lower rate such as with house hacking and making the investment your primary residence, requesting a significant closing credit from the sellers for standard rate buy-downs (which I've had great success with recently), or utilizing lenders who offer short term rate lowering solutions such as 2-1 rate buy downs (again, ideally paid for by the sellers).

The first apartments I rented as the owner, were previously rented by the former owner at $150 month including utilities. 

Most likely raising funds from passive investors would utilize a Reg D 506 b or c safe harbor exemption from registration.  

I'm passionate about real estate and how utilizing this asset class can enable me to build generational wealth and retire early.

@Chris Collins  Tenants usually pay all utilities. 

However, if you intend to work with a hard money lender or utilize a short-term loan product, you're on the clock for repayment, which can be stressful if things go sideways. 

Smart tech, such as fast Wi-Fi, streaming services, and keyless entry, consistently gets positive feedback, as do luxury bathroom additions like plush towels and rain showers.

From experience with mechanical and utility issues in distressed properties, I would also wonder why the breakers were removed.

Each are great strategies to access capital and each has its pros/cons for utilizing the strategy in the best way.
