Refinance out of HELOC - Is there a seasoning period??

[Nick Vehr]

I've been confused all day, thinking I may have heard my loan broker correctly. But can someone please clear this up for me. 

Let's say I take out a HELOC for 100k, and spend 75k on buy and hold after expenses and rehab with an assessed value of 100k...

I then finance the 75k, it into a fixed rate mortgage, and pay off the HELOC.

Will I need to let the HELOC season for 6 months in order to do that, or would the fixed rate need seasoning. I'll admit, im a bit confused here...
