1031 debt replacement

[Nabeel Kurji]

HI- im in the middle of a 1031 and our loan might not be approved.  is there a way i can shield myself from tax liability by just paying the debt amount that needs to be replaced with adding that amount of cash into the deal and then refi it later?  would this be considred the same as replacing the debt with another loan?

what constitutes debt replacement?  

-can i add my own cash as described above

-can i take a loan from a friend 

-or does it have to be a bank loan?

thanks in advance
