Assignment fee situation and questions

[Christopher P.]

[b]Seller asking for $175,000(firm), market value is $230,000 and ARV is $330,000 minimum. The end buyer is a investor looking to close all CASH and will pay for closing cost. Both sides will be aware of the assignment fee and the profit margin.

[/i]-If the investor decides to fix&flip, can the assignment fee be as much as $15-30k without performing a double closing? which process would be easier when it comes to big numbers?

I just read a blog before posting this about some dude who made $15k a flip on assignment contract NOT double closing. But most the forums on here are saying to double close instead when it comes to big numbers. However, I do know that some lenders will not lend to buyer to pay the assign fee, which we'll have to perform a double close in that case? but I did mention it will be a CASH buyer.

If you're giving me an answer that the assignment fee are limited and double closing is the way to perform such a deal, Why?

What's the most you made on assignment fee?

Thanks
