Present Value of a Tax Free Standby Line of Credit

I’m working with a couple who have a free and clear property but want to understand the difference in impact on their portfolio in 20 years if they have a Line of Credit in place

i.e. the cost now of the FHA UFMIP and closing costs spread over 20 years and if they have a 2MM standby line of credit in 20 years, that they can draw tax free

should make it’s own case for it being worth the upfront expense

calculator for that already in the quiver?
