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. 

Hello,I was hoping to receive some advice regarding the best business account to use specifically to handle larger wires on a tight timeframe. 

Account Closed I purchased a vacant lot a few months ago and am looking to build. 

We currently max out our Roth 401k, Roth IRA, and $2k per month into our vanguard taxable account.

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. 

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?

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. 

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

Account Closed you have the cost of the mentorship incorrect.

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