This indicates you either have a ton of debt or a small income (i'm guessing small income) more insecurity"we're getting there but by that time it'll more than likely be too late to build the wealth I would like for us" This indicates either ignorance or impatience/immaturity on your part (don't mean it harshly).

They may be trying to dodge debtors, as mentioned earlier.

Contract the work out and expand faster at the cost of carrying greater debt OR Do the work yourselves, expand more slowly but preserve your capital so that when you do expand, you carry less (or no) debt into the next deal. 

The "debtor ... shall be afforded the opportunity to show cause as to why the foreclosure should not be allowed to be held.... the debtor has the right to appear at the hearing and contest the evidence that the clerk is to consider under G.S. 45?

If it was reaffirmed, the debtor is personally liable for the debt again. 

They only auction the rights and interests of the tax debtor and it's not uncommon that there is another or other persons on title that could conceivably be your real estate co-owners. 

If your note and the circumstances surrounding your note (such as information provided to the debtor, disclosure requirements, etc ) either do not comply with, or lack evidence of all compliance features with these two governmental regulations then your note will be unsalable at anything but severe discounts.  

I've been recommended to several places by other investors that aren't exchanges, but hedge funds who are the originators of the debt, or pool the debt together, and then sell it out.

It's up to the lender if they want to go there and not seek any judgment against the forgiven debtor.

You need to reduce the note to a judgment against the debtor before going after other assets such as the personal residence.
