First time BRRR how to handle real estate agent pre-approval?

[Todd Staples]

So I found a great BRRR opportunity quad MF home that is gutted down to studs. Good news is the deal I THINK I can get would buy the house for 200k, rehab costs about 80k, and ARV of 500-600k. This is the worst house in the best neighborhood in town, super hip in the most desirable area. I've had a few contractors walk through so I'm comfortable with the repair estimations. My question is this- all the hard money lenders have told me make the deal first and we will get you financed one way or another. But my real estate agent is asking me to show her a pre-approval letter before she'll make an offer. Any way around that?
