Flipper Open to Sellers Financing

[Account Closed]

Hello! I am ready to buy my first property- Here is the situation:

The property I found is a flip from someone that got it from a wholesaler. It’s rehabbed but they didn’t do a great job aesthetically but fixed the hvac and floors. It has been listed for 102 days now. 

I contacted the listing agent and asked if they are open to creative financing (seller or subject to) and the answer was yes, however send a prequal letter or proof of funds statement. Does that sound right? I thought with seller financing it’s just the offer and terms then negotiate from there? 

Edited to add: property is a small condo I will MTR to travel nurses that will cash flow at least $800/mo after I ran the BP calculator
