I'm unsure if you would be able to combine both loans given that the HELOC is tied to a different property than the one you got traditional financing on.A work around is if you are able to purchase the new property with the HELOC at a significant enough discount, bring the property value up via renovations or additions, then refinance the property, pulling out enough money to repay the HELOC. 

.* Additional Charges: Jenny requested that I deposit on her checking account an additional $20-25k for her to purchase furniture, which I refused because I thought it was very strange, opting to give my card # instead.* Work Quality: Jenny never showed up to the house, she sent 2 people instead, she never mentioned she would not show up herself, she never asked for approval to send two others instead, they did not complete the job, and there were multiple unauthorized charges on my card.* Receipts and Expenses: Once I brought to Jenny's attention that we were 20k above budget, she refused for days to give me the receipts, saying that I needed to give her my credit card statement first.
