The repayment terms for a 401k participant loan are equal monthly/quarterly payments of principal and interest (typically prime plus 1%) over a 5 year term (longer if used to acquire your principal residence).Please note that if you take a full $50,000 and then pay back the loan, you can't take another $50,000 until 12 months after the first loan was fully paid back.Per the loan offset rules that went into effect with the 2018 Tax and Job Act: if you leave your job and the loan is current at the time you leave your job but then the loan goes into default because you left your job, you will have until your tax return deadline (including any timely filed extension) to make the loan current by depositing the outstanding balance into an IRA (and thereby avoid the taxes and penalties that would otherwise apply).

I used that map to find properties I wanted and also took my laptop, extension cord, etc. to the sale and would pull open the map and see each property as it was auctioned off.The auctions are fast...you have to be prepared to bid fast.York County takes business checks also...so I was able to pay for the liens with my business checks.Here is my final map:  https://drive.google.com/open?...

Challenges for this one is that the winter can slow things down extensively Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

That included an extensive amount of earthwork as the land that we had was not most ideal.

Be sure to check for pre-payment penalties, and extension availability/fees. 

Considering your HELOC is a 4% interest I would personally consider it an "extension" of your mortgage.
