This is a skill to practice and build up your tolerance for doing.That being said, whatever you use the money for has to cash flow and pay back the borrowed money for you.I don't think the HELOC you arranged is necessary bad.

Do you have financing arranged? 

I'll contact you outside of this post to arrange the details.

At the Balloon payment, arrange for purchase to be sold to end buyer, and collect 6 figure commission check.This would probably be the most work I've ever done to get 6 figures, but is it worth it?

Your employer would have to surrender a lot of control over your job in order to switch you to 1099.Third, even if you arrange such a switch, it comes with a heavy price tag:- you will owe the employer's portion of Soc Security / Medicare taxes, basically an extra 7.5% tax- you will not be eligible for the employer benefits like insurance- it will be more difficult for you to obtain unemployment benefits when the job ends- the most important one: you're extremely likely to fall behind on IRS taxes, because they will no longer be taken out of your paycheck, and you will have to save up yourself and pay the taxes quarterly.

I would also let the one your not choosing know today so they can make other arrangements.

Alternatively, if you have liquid assets over $750K and have an account with HSBC/Citi/JP Morgan in the UK/Canada, your banker should be able to arrange financing in the US (not the same terms as most US folks would get). 

if so what have you seen recently for each arrangement?

She’s technically an agent, we have our own arrangement, but definitely worth at least reaching out to.

Hey BP,Looking to make this a sounding board for inspiration for how others have partnership arrangements.
