Trying to understand hard money

[Ray San Miguel]

I know there are a lot of people in the hard money industry that can take advantage of newcomers so I figured I would ask the BP community. I understand the idea of hard money lenders, But how does it break down? How do you know if the terms are good? I am looking at a property that requires cash offer only. I want to fix and flip it and pretty much needs a full rehab. List price 390k probably will sell for 420k. The ARV based on comps are 520-550. Thanks guys!
