That's a very real concern (definitely one I had when I was starting out).

If your concern is positive cash flow, you are typically less concerned about when you pay off your debt because the goal is the positive cash flow.

But, after having taken care of that immediate concern, it'd be even greater to then be able to get a regular 80% LTV cash out refi (after whatever seasoning time is required) on the very same property, because that would allow them to include the equity they've added, whereas that added equity (added via performing the rehab) is apparently not able to be included in the Delayed Financing's LTV.
