In case your building is a very small building, install a lock box in hallways, a place that is a bit protected of the weather and not being in plain view.

I've considered it but have not executed.In regards to the heloc if I understand things correctly you will not be able to take out a heloc on a investment property but simply a loc or a blanket/commercial loan depending on the financial institution you decide to approach with the situation.

The bottom line is that self-directed Solo 401k can be great tool for you in your overall financial planning and wealth building plan. 

I read a really good blogpost, https://www.biggerpockets.com/renewsblog/2015/05/10/invest-out-of-state-how-to-analyze-a-city/ that talks about a city's Comprehensive Annual Financial Report (CAFR).

I am a IT Professional who has a love for financial planning and passive income.
