Question about 70% rule

[Account Closed]

I'm new to real estate investing and just starting out and looking to start my business in about 3-6 months. I did a example deal and used a property that is $91,250. the house already been fixed up so I used the formula without any repairs. I got $63,875. Now would that number be what I offer a new investor or do I offer him lower than that. And what number would be good to offer the buyer I'm buying the house from?
