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).

if my lease says any payment is first applied to outstanding fees etc... what is the best way to approach this?   

its amazing on BP its pro wholesaling and finally one absolutely out standing individual who actually understands the ethics behind most wholesalers.

Yet San Diego financed buy n hold would have produced outstanding ROI (averaging better than Houston).  

Consult with your attorney but I would expect your lease provides that tenant is in default for late payment, triggering numerous default options (acceleration of outstanding rent owed, right to evict, etc.) for you as LL.

Wanted to update my timeline and post a couple of outstanding questions I still have.

One other note, if you want to collect on your certificate by sending to a tax deed auction (where you have no advantage) you must also pay off all the other outstanding certificates, so you could be into for 5-10 times your initial investment.

Moreover, the disadvantage of the HELOC is it can have a low starting interest rate, with a variable monthly rate based on the outstanding balance, vice if you have a fixed rate loan when you refinance. 

Hi Victor,Look at the size of your outstanding debt.  

@Chad Smith@Chris Mason1) Regarding taking a 401k loan: You would have to confirm that your 401k plan allows for a 401k participant loan (and that you have not had a outstanding loan in the last 12 months since your ability to take a loan is reduced by the amount of the highest outstanding balance of any 401k loan that was outstanding in the last 12 months).If yes, you can borrow up to 50% of the balance not to exceed $50,000.The repayment terms are equal monthly/quarterly payments (as you prefer) of principal and interest (e.g. prime + 1%) spread over a 5 year term (or longer if you will use the loan to purchase your primary residence).
