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

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.  

Wealth Building vs Cash FlowMy proposition is that too many real estate investors, much too often, emphasize cash flow over increasing net worth.

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?

If you want to go the "cash for keys" route, there is no specific formula or legal limit, it's just something you negotiate directly with them. 

Have you considered ways to increase the rent so it actually produces a cash flow return?

Purchase price: $175,000 Cash invested: $750,000 Sale price: $1,450,000 This is a current transaction that I'm working on.
