What's a reasonable percentage for me to get for finding a deal?

[Devin Bost]

Almost everyone says you can get started in real estate with no money. Well, let's say that I spend a lot of money and time on marketing and due diligence and finally find a great deal on an apartment complex. Let's say it's a 10-unit complex. Now, let's say that I need to find equity to pay for the deal since I used up all my money on marketing. The property is very attractive for investors because it beats the 1% rule, is in a prime location, needs minimal rehab, and the market trends are all extremely favorable towards this property. Let's say I get it under contract and make all the necessary arrangements. What's a reasonable percentage for me to expect to retain in terms of ownership on the property? I've heard some people saying as high as 10% since the deal is so good that investors don't want to say no, and I've heard as low as 1% for those who just consider it a "finders fee." What's a reasonable percentage that I should expect?
