Heloc from primary residence vs Heloc from investment property

[Jason Y.]

What are the restrictions on taking a HELOC from a primary residence vs taking a HELOC from an investment property?

I heard that HELOCS from a primary residence is usually used for remodeling and cannot be used for investing in another property. I am trying to verify that statement but can't find the answer. The idea is to take out a HELOC to outright buy an investment property in cash. Does it matter if you take the HELOC from primary residence or from investment property? Will one have lower interest rate or favorable rules vs the other?

I read this article and it says that HELOCs from investment properties are harder to get but HELOCS don’t have restrictions on how they can be spent.
