House flipping . Understanding the process

[Jerell Edmonds]

Hey BP Fam this might be a dumb question. My co worker flips house and every time I pick her brain I fully don't understand the process behind house flipping esp the lending process. She basically broke it down like this . She has a private lender that's been working with her & husband for some time now . She told me just like this hire workers that do great work , have a timeline for the flip she said about 3 months is a good time another thing that I  found interesting if they don't get it done in that timeframe the lender charges them an extra 1500 each month until home is sold to get money back. So my question is for flipping a home do you get the desire amount you need for the entire flip using lenders money or do investors throw some of their own money into the deal? I'm just lost on that part she really never goes into much more detail after that. I'm just curious on how it works.
