How people scale at a fast rate

[Brandon Montgomery]

I realize using the BRRR strategy and pulling equity to reinvest is one of the best ways to scale, but I often read success stories that don't add up to me. If you're starting with very little money and it takes 6 months to cash out refi wouldn't the max be 2 in the first year assuming you used most of your capital on the first one? Obviously you could end up with more equity pulled than you began with but I often see extreme numbers of units in a short time frame and have yet to figure out how?
