Financing options for self funded searchers planning to hold permanently

I'm a self-funded searcher planning to acquire and hold permanently, then continue growing through additional acquisitions over time. The challenge I keep running into when thinking about bringing in outside investors is that most LP structures assume a sale event to deliver IRR. If I'm not selling, traditional equity terms don't really fit, assuming an IRR between 30%-40%. A few things I'm trying to figure out in regards to financing options: - Do most permanent-hold searchers stay away from outside investors entirely and stick with SBA + seller notes + other forms of debt? - Are there investors out there who prefer consistent cash flow over a terminal sale? If so, what do their terms look like? Appreciate any perspective from those who have financed a permanent hold deal.
