Using primary residence equity to place an all cash offer?

[Luis Vecchio]

Hello everyone, I'm looking to buy my first property and have been striking out. I have significant equity in my personal residence, enough to purchase a house outright in my market. Would it be feasible to take out equity, from primary residence, to buy a house all cash and make my offer more appealing? If so what means would be the best to do that, a HELOC, cash out refi in my primary residence, etc? Thanks for all the help in advance!
