401(k) loan, cash flow during payoff

[Peter Beckwith]

I’m on the hunt for my first rental property. I have some decent cash savings, but I will need to take out a 401k loan to cover a chunk of the down payment. During the loan payback period (I’m targeting 3-5 years) the cash flow on the rental would be low because the monthly loan payments. Does anyone have experience with this and is it worth while to get low cash flow for those years ?

Here’s some numbers. $20,000 loan at 4.25% is $85/wk payment, which is about $368/month
