Refinance with JV Partner

[Michael Majer]

Short question: Is it possible to refinance a property purchased under 1 LLC, but JV'd with a partnered LLC (not on deed) into a long term mortgage?

Purchase a property on hard money with intent to flip. Partnered with another LLC not on mortgage. Ran into significant sewer repair that was completely unforeseen even after camera. Has completely crushed rehab budget and set us back significantly in timeline.

Internet was to flip, but wondering if it's even possible for us to refinance and rent it now. Issue is we have the JV partner and they would like to be part of the ownership if we long term hold. We have great relationship with the partner and would be open to long term hold together if that's our last resort. I just don't know if we can refinance it into a long term mortgage with 2 LLCs even though my LLC solely purchased.
