Refi cashout option to paytowards primary to extend heloc limits

[Stanley Dean]

HI BP community- while await on finding the right potential investment property for the right price. I am contemplating to using if this is good strategy. I am thinking of doing a refi 30years in an investment property and do a cash out and do a refi cash out on a Vacation property that was bought for cash and rehabbed and then apply a combined lumpsum payment to my primary home that I am paying a good amount in interest $1200 and there by increase equity and get a heloc open for use for the next coming investment. I am thinking this will save me a good amount of time and interest on my primary and have an open heloc available for pay for a potential investment rental. Please advise
