If the 22 + 70 acres appraises high enough to cover my mortgage, can I own the 8 acres parcel/building lot free and clear and pull a HELOC on it?

Go to a construction site (production home builders--- Toll Brothers, Orleans, KHov) and find the carpet installer.

You can literally find answers to all of your questions within the confines of this site.

Assuming the property is appraised at $650,000.00 I am hoping the equity will get my LVT to 75% eliminating the PMI, adding to the potential cash flow when I go to rent and then putting that cash flow + personal savings away to raise capital to buy another piece of property.I realize that in order to buy my next piece of property I will want to put down 20% to avoid PMI and a high mortgage but saving 20% for a piece of property in my area is going to take some time due to the high price ranges $500,000-$700,000.

I would recommend that you sell as yourself and buy as a disregarded LLC. 

MAYBE you could get the court to garnish wages, but that's highly unlikely. 

your credit score would not plummet, but you are still responsible for the debt so it will still show up on credit and it will impact your ability to get credit.The only way for her to truly buy you out is to refinance and take your name off of it.My recommendation would be to sell the property, as you may be on good terms now but that does not mean you will be on good terms in the future.
