How to fund my next flip with equity/hard money lenders

[Jacob Rincon]

Hey BP community,

I have just finished rehabbing my first property and i'm looking to put it on the market by the end of next week. The profit I'm making from this flip is pretty much all except about 20k going to clearing past debts. so my question is, how can I fund my next flip that i've found with a purchase price of 507k? I currently have found a lender that will lend the 80% of the purchase price, now i need to figure out how to get the 20%  down and rehab cost of about 70k. 

I have not yet sold my first property, how can i use the equity i've made from my first investment property to cover the 20% down? I'm not 100% familiar with line of equity and how that works if i intend to sell the property. Can i still use the equity line and then sell the property? Would love some advice on how to fund this next property.
