Most people are using the HELOC almost like a bridge loan until their projects are done or they can get a long term fixed rate. 

The two  multifamily deals I am in are having a cash crunch from their bridge debt due to rates, and will need to raise funds to remain solvent if and when they get fixed debt.

Are there any bridge funding suggestions?

With the amount of bridge loans coming up in 23-24 there are lenders very aware of which properties might be on the precipice of failure.

There is obviously the liability risk of doing that, but there are still some great options for either bridge or long term debt in your personal name with non-conventional sources. 

@Jordan Jacks has a solid bridge program for acquisition and value-add commercial multi-family. 

I know I am impatient haha, is there any other way you suggest to bridge that connection?

Situations like a flip, BRRRR, using it to pay cash on a property that does not qualify for conventional financing (to BRRRR or flip ideally), or to bridge a gap to seize an opportunity if you know if you have money coming in a few months (from the sale of another property or something like that). 

There are multiple options like CBMS, Bridge Loan or Apartment Building with 20% from Fannie Mae. 

@Christian Konn, we have a bridge loan that allows you to buy the property and hold it while you work on permits, entitlements and plans.
