Need advice: Making investors happpy

Thank you for your time.

As a residential private hard money investor what would be a product (loan) that if you could design you would?

I have found that with some products you can please some investors. There is rarely a product that will always please all investors (If I could create this I would).

I will listen to what you have to say. The main goal of this post is to learn from you.

Thank you.
