Is this HELOC/ loan strategy a good one?

[Anthony Reyes]

I am somewhat new to this and wanted to get some of the pro's input. I have a rental property that I am able to get a HELOC on for $43,850. The APR they are offering is 7.75%, which I think is somewhat high but I'm new so not too sure. Houses around my area average around $150-$180k so I would need a conventional mortgage as well. I do not want to have to pay the HELOC an conventional mortgage together so I am thinking of flipping a house, hopefully done in 6 months and pay them both off and then use the profit to roll into a long term rental. Is this the best rout to take? Any input on this strategy would be greatly appreciated.
