My initial strategy was to buy a rental, rent out the rooms individually (separate lease per room), save as much as possible, buy another rental once I've saved enough, then continue the cycle until I've replaced my salary with cash-flow to quit my 9-5 and raise my kids.The problem is, my debt-to-income ratio is now about 40% and can only qualify for about $400/month more in additional loan/debt payments.

As I think about my business and after marketing is consistent and at maximum scale for one individual to handle I need to replace me.  

I would have anywhere from 1 to 3 individuals contributing to the project.

Hope that helps.How do you or do ypubrent individual rooms?

While I don't see the big issue with your rent numbers (all depends on the individual situation of all people involved there) I would definitely pull out as much money from the units as is feasible with respect to a still ok LTV (don't overleverage; rents still need to support all costs) and then use the money to make use of the current interest rates by getting mortgages, meaning of course: buying something.

I am talking about the individual unit doors that enter into the hallway.

I am also going to make sure I have all the relative facts and figures compiled into one report for individual properties that I could potentially show any investors etc. 

I got started when I bought my first single family home in 2007 and essentially fixed it up myself so that I could learn how difficult or not difficult each individual task would be.

Predators (and they are predators) know that you must discharge your weapon for reasons such as self-defense, but these individuals will shoot you for no good reason and do it when they know you're not ready.
