This is the ideal scenario for seller finance.

@Mindy Jensen Maybe it's all just individual preference?

Quote from @V.G Jason: Elon is like any real HNW individual, but just doesn't brace himself in the public eye.

So almost a little if both would be ideal.

The online platform is ideal for tracking all of that and more. 

So, while in some ways its great in others its less than ideal.

How much time / cash / other are each individual expected to contribute?

Bank of America’s business credit cards seem better, but I’d need to hit their Preferred Rewards status to reduce fees, which might be challenging.Amex: I like Amex’s reputation and services, but their outgoing wire fees are higher, which is a downside given how many wires I send.My ideal solution would be a business account with minimal wire transfer fees (especially outgoing wires) and a solid business credit card option, preferably with no foreign transaction fees.What would you recommend for someone like me who does a lot of outgoing wires and occasional foreign transactions?

I deal with manufactured, modular and site built. 

Then split bottom line 50/50 with the partner (individual) after all other expenses are paid.
