How Should I Pay for Repairs?

[Samantha Epps]

Hi y'all, 

Just purchased a 3 unit property that needs 40K in structural repair before it can be rented. I'm considering the following options to pay for these repairs:

-- Cash-out refi on another rental - I could prob pull 30K-40K out after closing costs but would lose my low 3% interest rate. Even after the refinance, the property would pull in considerable profit, and the cash-out would cover most if not all of the repair costs. 

-- HELOC on 3 unit (which is also primary residence)

-- 0% Interest credit card 

I'm inclined towards the cash-out option because it wouldn't directly eat into my cash flow, rather it would cut into my profits on that rental. Are there any other options I haven't thought of yet?  Which one of these options would you choose? I'm a small multi-familiy investor and if I play my cards right on this property, financial freedom is on the horizon.
