Seller has active Ch 13 Bankruptcy - Can I acquire Sub2?

[Dara Abasute]

SITUATION: Seller has an active bankruptcy and wants to sell b/c she's relocating. She would negotiate a short sale with lender if necessary, and I'm wondering if subject to is a viable way to acquire this deal or if it even is a [doable, good] deal at all. The trustee she's working with is aware she wants to sell her home. Seller is willing to "discharge" her bankruptcy to get a creative deal done if possible.

DETAILS: 

• - Seller filed ch 13 in 2019. 
• - Mtg payoff amt $137K
• - PITI $917/mo
• - Lender states borrower is 14 payments behind ($917 * 14 = $12.8K)
• - ARV $207K
• - Repairs: none
• - Avg. Rent: $1300/mo
• - Seller wants $5K to help with her move

QUESTIONS: How would one structure a subject to in this situation? Will catching up the back payments (and seller paying off legal and trustee fees) to discharge the bankruptcy suffice in making sub2 work? Is a short sale the better route (I've never done one before)?
