Turn time on flip house help

[Sam Hickey]

I am new to flipping but shooting out the gate. I have successfully sold my first, second is listed, and under contract to buy 4 more over the next three months. I do have a partner and we are bankrolling the down payments ourselves at 20% equity with a local bank for additional financing. My question is. My second house is listed for 99k. I believe it will sell at that price or close but maybe not as fast. I believe I could sell it really fast at 85k ish... I have 67 in it after commission and all. Is it better to sell fast ( hit singles) and re-invest in the next flip or wait to make the most per house. I can see the logic going both ways but would like to hear from some experienced flippers. Thx.
