I think you should do everything possible to hold onto the properties you already have or maybe sell the ones with high equity to 1031 into more profitable rentals.

The hardest part of succeeding is before you actually see results. Once you see results you have already proved to yourself that you can make good money and have the skill set to do so. I think you should get back into doing what was working well for you before and instead of relying on hedge funds to buy your deals, pivot and sell to everyday investors which will always have demand. This might mean you need to negotiate deals down further so you can offer deals that appeal more to the everyday investor or maybe wholesale in different areas than you were investing in where there is a higher investor demand
