The result is an even deeper inflation than what we already suffer from.

Even though no prepayment is possible, we are quoting a lot of 1, 2, or 3 year prepayments. 

I ran the numbers on the deal knowing that I would break even on cash flow in the first year with minimal rent increases but significant cash flow in year 6 when the 401k loan is paid off.

@Rae Chris, finding a "0% down" loan is hard, if not impossible today, even with your first property as collateral.  

It's hard to find bankers who have even heard of a series LLC.

Just looking at their website,  there is no useful or helpful information that a sophisticated investor would normally require (to even give them a chance of being considered).
