@Michael BaradellWith 20% down, 30-year fixed interest rate mortgage, completely turnkey (rehab completed where the seller fully extracts the value-add), subtracting PITI, 8% vacancy, 10% PM, 5% maintenance, 5% cap-ex, absolute minimum would be $100/door, ideally getting $150/door or more.

There are still some new projects that can be worthwhile investing in just have to be careful on how many years are planned to extract the value and strength of the operator.

Any sponsor that can get agency financing with 10+ yr rate lock is able to mitigate their downside risk and enable the asset to cash flow through a buyers market. 

It enabled us to leverage our situation and pay for schooling, which neither of us would have been able to do without this investment.

It’s guiding our investments because we actually set a target ($100,000 passive income as a couple in the short term and $150K+ in the long term) and are currently building the seed capital that will enable us to hit those targets. 

Otherwise I am going to sell my current home which will enable me to get a house.  

Debt or "leverage" only enables you to buy something that you otherwise could not have afforded.

Lack of reservesThe one enabler I would add to @shiloh lundahl advice is if you don't have sufficient reserves - partner with someone who does.

When class codes are enabled, every transaction can be assigned to a class code and from that information, you can run a Profit and Loss Statement not just as a total aggregate number but broken down by each property.

However, having gotten it, it has afforded me skills useful to many parts of my life, and has enabled me to get experience that helps me to evaluate properties in a unique way.
