Will rent out the unit we’re leaving which covers about 65% of our new mortgage, if we pocketed it but that stays in the rental fund. 

I own several hundred rental units in other states, otherwise I'd join you in helping cover the costs.

This helps determine if I would be responsible for covering those costs.

Lenders typically look at the rental income of the property to determine if it covers the loan payments.

I would offer it on a land contract to someone wanting to live there for around 1500 and small down payment or sub2 with a large down payment and monthly that would cover PITI.

So most agents are only putting about half of that $12k in their pocket, and out of that $6k they have to cover all of their operating expenses: licensing fees, MLS/ Realtor Association fees, continuing education classes to stay compliant with licensing requirements, monthly "desk" fees/ technology fees to their brokerage, health insurance for themselves and their family, errors and omissions insurance (required), marketing, car, car insurance, gas, clothes, computer/ software, cell phone, closing gifts, signs, photography, staging if they offer that, etc.

They will sometimes cover some of the damage with lots of back and forth.Look into companies like Waivo and Safely.

Or we print xxxxx dollars to cover our interest and debt payments.  

The covered majority of the lost rent.

There will also be a new front deck (and back deck eventually), and a small covered porch with a hipped roof.
