Relocation: Is the lump sum tied to selling via GM?

Hey all - quick relocation question for anyone who’s been through GM’s U.S. relocation program recently.

For homeowners: is the lump sum relocation allowance contingent on selling your house through GM’s relocation partner (preferred realtor), or are those two things separate benefits?

In other words, if you relocate but either keep your house or sell it independently, does that affect the lump sum, or does it only matter if you opt into the home sale assistance itself?

The policy language feels a bit ambiguous, so I’m curious how this worked in practice for people who’ve gone through it.

Appreciate any real-world experiences 🙏
