Fastest way to get invested cash back in an all cash purchase

[Lindsay G.]

Hello, I am in a position to make all cash purchases for rental properties (either turnkey or recently updated, NO rehab) using a HELOC. What is the fastest way to get that cash back to pay back my HELOC after purchasing? Is there still a seasoning period when a purchase is all cash? Do I get a private lender first and then refinance with a bank if I do have to wait for a seasoning period? What if I'm using a LLC? Thanks!
