@Adolphus Fletcher - If you're main goal is to build business credit there are different avenues to do so including: obtaining and unsecured line of credit for the business, applying for a business credit card, applying for business accounts such as Home Depot/Lowes, etc...

I'd attack the credit report :) 1) lower (pay down) whatever accounts have a high utilization percentage 2) contact each of 3 major consumer credit agencies and get a free report, then dispute every hard inquiry that is *NOT* associated with an open account 3) call the credit cards you already have established and ask for a credit line increase -- often can be done online and they do not verify income, hint hint.

If we had gone through with the transaction and somehow obtained right of first refusal written notice, would the seller be legally held accountable without us forcing litigation?

1099 C is an interesting question ask your accountant.. note holder asking to be paid off . this is just a negotiation.. you offer what you want to offer and they can accept or deny. 

Are there any good resource recommendations for learning accounting for a project like that?

I highly doubt you'll find anyone here, but DM STR accounts on Instagram may help you connect with a host who has done it. 

Make sure you get regular statements of that account to make sure they are not tapping into the deposits.

You cannot invest what you do not have.Initially before you invest, your success is measured by how much you have in (for instance) your Vanguard Money Market Fund, or an FDIC insured Money Market account, or stuffed inside your mattress, etc...

You sound like a child who got into their dad's account.
