Mortgage, HELOC or HEL? For extra cash for investing.

[Patrick H.]

For a property that does not have a mortgage, what is the best way to get cash out for investing purposes, whether it is for another property purchase or putting the money in the stock market.

A HELOC or HEL is possible, and since it will be the first lien, I would think the rates would be below 4%. Is is better to just get a lump sum (HEL) even though I would be paying interest right away, but will lock in the rate.

I don't know if I can just get a regular mortgage since the HEL seems similar.
