If they are the prior debtor, you could offer them a cash-for-keys-agreement for an amicable move out/no damages; a signed, written agreement to exchange $$ for their keys so they move out on a specified date with no damages and all utilities still on.  

@Christopher Giannino - do you think if you knew you couldn't pay down any type of significant portion of your student loans within the next 10-20 years that you would have leaned toward house hacking your way out of student debt? Or

A bad credit report with low scores, judgments on outstanding debt, or an indication of major debt, can give reason to reject an applicant.Feel free to direct message me if you want to chat a little more about this, I have some good resources I can share.

I have enough cash to either clear out all my debt or invest in our first property.Clearing the debt would save us $670 every month. 

Here's the more-or-less official definition of a credit score: a numerical representation of the likelihood of the the debtor going 90 days late on a payment in the next two years.The credit report is what really tells the story.If the applicant is open to your proposal, you could probably proceed.Be aware, however, that until the divorce is final, the tenant's credit situation remains in flux.

Learn as much as you can and pay off all your debt or close to debt free as possible.

The difference will either be new debt or new cash. 

Anyone can file the lien, but it's nearly meaningless.2) 90 days after filing, the contractor would have to take the debtor (owner) to court.

I have cash, and 800+ credit rating, and except for a primary residence have no other property, debt or mortgages.Who else has done this?

They have so few assets and make so little money that the courts will not order wage garnishments so creditors just have to hope a) that the debtor improves their situation before the debt is past the statute of limitations if waiting to sue for a judgement or b) that the debtor doesn't bankrupt on a judgement if already awarded.
