@Michael Cavalli it sounds like you’ve put a lot of time, money and effort into the house. I’d look at it from a few different perspectives, you could rent one unit and live in the other one, you could rent both units and move somewhere else or you could sell.
First, figure out how much each unit will rent for. Check out rentometer.com to start. Then see what your costs would be (mortgage, insurance, tax, etc.) Does it cash flow or are you paying to keep the property even as you collect rents?
Next, take the projected cash flow divided by the amount of money you've put in to get a projected annual return on investment (ROI). Is it 2%? Is it 10%? Is it 20%? Is it negative?
You can also try to refinance and pull your money out which will increase your ROI, but reduce your cash flow. If the projected cash flows are negative in every possible situation then I would cut my losses and sell, as hard as that would be.
Hope that helps. Good luck!
