How can I structure the contract or investor payout terms to ensure they feel secure and confident in receiving a solid ROI?

I would just get with @Dave Foster and have him walk you through it and get it taken care of.

The county is the second fastest-growing in the U.S. and the fastest in North Carolina.The zoning for the project is already approved, and with our captive audience of potential tenants, I’m confident that all units will be leased upon completion.I’m seeking advice on how to best structure this debt with a private investor or investors in the short term until the property is fully rented and long-term financing is secured.

That company supports foreclose bidders they produce a document daily on all the sales with same info I mentioned above and color coded certain props with extra caution Red or Green for ready to go bid with confidence. although this created uber competition. 

It helps me feel more confident about the numbers before moving forward

Moreover, it fosters resilience, as investors learn to navigate the inevitable ups and downs of the market.

I am not sure if anyone ever cared to pull together the data but I am quite confident in saying a study that compared licensed to unlicensed contractors would tell the story of unlicensed contractors seeking greater deposits in relation to total project costs than those with all proper licenses.

Once you’ve got some experience and equity built up, you can more confidently move into multifamily properties when the right one comes along.That said, if your goal is to scale into multifamily, don't lose sight of that.

Don't get sucked in to borderline applicants, make it as black and white as you can so you can approve or turn down with confidence.
