@Doug HallNo, you do not need a custodian for a Solo 401k and a checkbook 401k gives you the additional control and flexibility it is known for by circumventing the custodial middleman.

That will affect things like cash flow, etc... but I feel that the flexibility it offers is perfect.  

Simple answer is that any broker should be flexible and commissions are negotiable.

In our rental agreements we often use the term MAY, so we have some room for flexibility and for cases where there are extenuating circumstances.

I have had to recreate that (in a modified, more flexible form) for myself. 

The good thing about the HELOC is that your payment is more flexible.

Have been looking into local, small brokerages with more flexibility!

So it was pretty close to a traditional mortgage but it did effect the wiggle room in cash flow vs flexibility in rent price.

It gives you great flexibility and can provide you with a financial benefit if you do enough deals and are okay with keeping up on continuing education.

Unlocking the doors to the internal stairways would provide the flexibility to utilize the four single family residences as the functional equivalent of a small Hotel or as any combination of 2, 3, or 4 residences.One advantage, to permitting such a building as a multiplex instead of as a hotel, is that Medium Density Residential (MDR) zoning required for a fourplex is available in many more places than is the commercial zoning required for hotels.
