What about funding the Rehab in the BRRRR method

[James Boprie]

I've been getting up to speed with the way that the BRRRR method works but I'm stuck on the Rehab, specifically how to fund it. For example if I only had 10k and was using every penny of it for a 20% down payment, how do I fund the Rehab? What are some strategies out there that have worked? I'm not posting this out laziness, I just haven't been able to find an answer for this particular question.
