Funding a remodel options???

[Davis Stoner]

I recently purchased a small multi family property. 2 units were turn key and they are rented. 1 unit I am funding the rehab for and that is almost done.

But there is a separate building with 2 unfinished 1Bd 1Ba apartments. My estimate is that it will take between 50-75k to get them both rent ready. 

I wanted to see what everyone's thoughts were on financing the rehab? I do not have enough cash to fund everything, and I don't think there have enough equity in the home to take some money from there. Hard money is definitely an option but does anyone have any other possibilities to explore?
