Heloc on a seller financed deal possible?

[Tyler Fisher]

At the end of the year i will be acquiring my 4th house. This will be a seller financed deal with family, it will be a full rehab but i will be purchasing well below market value (60K under) once i get it fully rehabbed and ready to rent am i able to get a Heloc on the property since its a seller financed deal? I am not looking to cash out refinance since i am getting such a good deal on the home being seller financed with such low interest and they are willing to finance the entire length of the loan (12 years).

Thanks for any insight
