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).Please keep in mind the multiple loan rules:Under those rules, the sum of the balances of a participant's outstanding 401k loans under a single 401k plan (using the highest outstanding balance of each loan over the last 12 months) can't exceed 50% or $50,000 whichever is less.

We are just so far in now I am trying to get this across the finish line...

I'm looking to get their "package" which includes a Holding company, LLC Subsidiary​, Corporate Financial Program and an Estate Plan.

Quote from @Beth Johnson: We pass all loan servicing charges through to the borrower including set-up fee, monthly fees, and any servicing charges such as payoff demand generation, and loan close out fees. 

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

However I have done them in multiple States including Pennsylvania and South Carolina, and what I can say is that it is a tool in your tool belt. when you come across a deal that makes sense to make this type of offer you can do it. the laws in your state make it difficult for you to do these types of deals I suggest either don't do them or pick a virtual market in which you can do these types of deals.

True, but (a) they were typically experienced investors, and (b) today's market includes record prices and high mortgage rates, which is a double whammy. 

In the pitch I include just a couple of my projects from the last year as a reference to my experience. 

To add value to the property, we undertook extensive renovations including the removal of over 40 yards of trash, installation of a new septic system and wall-hung boiler, and a new well pump.

I completely understand why that clause is there and I'm happy to have it for many reasons including protecting my tenants and my property from damage, etc.
