Once you have your goals outlined you can determine what the best way to reach those goals are and how to best use your HELOC.

My reccomendation is to outline a realistic business plan in converting the 16 POHs over 12-18 months.

Property taxes in these outlining areas will kill most buy & hold investments (except maybe in Chester).

What are the chances of your rights and entitlements outlined in an agreement of sale being fully exercised by you compared to someone representing you that's seasoned, especially when the potential buyer fails to uphold their end of the transaction?
