My goal is to purchase 15 units in the next 5 years, and produce a cash flow of $20k per month within the next 10 years.  

Is this a Rehab deal or a cash flowing property?

Yes not just for cash flow but for the health of the deal.

Hello Zachary,  You are correct in looking at the Mid-West for cash flow. 

Purchase price: $350,000 Cash invested: $10,000 House hacking my first home by converting the master bed into an independent studio that we rent on Airbnb What made you interested in investing in this type of deal?

Apparently they take preferred interest in your company or have you sign a UCC cash flow agreement.

Net worth and cash flow

Quote from @Carson Hyland: Even if you buy the right property, failing to manage it well will kill your cash flow. 

Unlike cash buyers or those with extensive experience in the market, many younger buyers are still navigating the mortgage process while actively house hunting.

I'm open to properties were cap rate is around 10%+ and Return on Cash is 10%-20%.
