I’m going to disagree with @Chris Seveney and say whether an assignee could force a sale directly would be a state law issue and heavily dependent upon the contract terms. 

What about having to break even, or even feed the property every month $200 for those same 36 months, but at sale, could net a $75K-$100K profit?

However, that made getting the ADU done within 180 days of the ORIGINAL sale of the relinquished property difficult.

Purchase price: $185,000 Cash invested: $35,000 Sale price: $671,000This was our 3rd home.

Purchase price: $2,000 Cash invested: $60,000 Sale price: $91,000 Bought this one from WCLB with the intention to fix it and sell on market to homeowner.

It’s awesome to see your excitement for real estate investing, and congrats on your first land sale, that’s a great milestone!

Purchase price: $160,000 Sale price: $170,000 Contributors: Peter Vekselman Partner Driven and Jamari Sprueil secured this Dover Ct property in Riverdale, GA, for $160,000 and successfully sold it for $170,000 on the same day.

I would recommend fixing it and then determining whether or not to sell based on cash flow and profit after the sale.

Purchase price: $395,000 Cash invested: $100,000 Sale price: $570,000 Such a fun project!

It is just like being in sales doing the prospecting, need to pick up the phone and call them.
