Military move 1st potential rental

[Aaron Ver]

Current mortgage with VA at 2.x% with 278,000 left in South Carolina less than 4k worth in maintenance. Comps show the home is worth around 420,000 in an excellent neighborhood with potentially low vacancy rate if i were to rent. Current credit score is about 640 with 30k worth of consumer debt between wife and I not including vehicles. Getting stationed in Newport, RI within the next 5 months. In order to purchase my next buy and hold, should I just sell the house completely due to short turnaround time, do a cashout refinance and rent, or take a HELOC in order to pay off debt and use the remaining on a down percent for the next property. Any information is appreciated. Thanks in advance.
