Essentially I didn’t make enough to qualify for this loan.

I recently flipped my first property and it was a cash purchase.

As you begin, it's essential to familiarize yourself with the key concepts and strategies that will help you succeed.First and foremost, building a strong network is crucial.

Which I currently still hold, and cash flow decently.

This is a single-family home in a commercial and multifamily zone, so I believe that if the right investor obtained this property, it could be acquired at a higher price due to its potential for significantly higher cash flow.I'm wondering if I can increase my asking price because of the property's zoning potential.

With the additional cash coming in maybe the next journey for you is figuring out how to diversify in another asset?

Meaning you have the actual cash to buy multiple properties in cash, then sell, flip, or do whatever.  

Purchase price = x Cash down = 0Owner Financed amount = x  interest rate = xMonthly interest only payments to seller = x 20 yr. term = x so on and so forth with gross PP?

The interest actually goes back to me so it’s essentially just an opportunity costs question about losing $50k of retirement investments with effectively 0% interest. 

You can't always get someone out immediately to fix things-you need to call right away (as soon as they open), but the rest is often out of your control and waiting 1-2 days for a non-essential appliance isn't the end of the world.
