I have now almost completely eliminated my debt, and replaced that debt with assets!

Bryan,Here are the 3 main options to consider:1) Custodial self-directed IRA, lower upfront cost but watch out for transaction and asset based fees, have to go through custodian for every transaction, might be inconvenient for certain investments. 2) Checkbook IRA (aka Checkbook IRA), eliminate transaction fees, higher upfront cost because of special purpose LLC, but long term will provide savings and most importantly a convenience of having checkbook control over your retirement assets. 3) Truly self-directed Solo 401k, requires self-employment activity or small business, the best option if you qualify.

I use my minimum scores to eliminate those applicants that I would otherwise be accused of discrimination against.

Ultimately I'm going to add a security door there but for now, to eliminate the problem, I boarded off the space.

@Joseph Illing You may be able to eliminate this problem through another method. 

Well you could eliminate your mailbox....

I can find out tomorrow if any are available.Another option is through the use of a specific type of trust, that will eliminate the timelines, and allow you to reinvest the proceeds when and how you like.

I'd like to refinance into this type of loan and use equity from the house for investment purposes in addition to eliminating a high volume of interest. 

This eliminates any risk of damage and amounts to less time then pushing back through and  pulling.

It's those maniacs that buy homes cash via quit claim deed off of craigslist that really get screwed.Make sure your property manager is a licensed real estate brokerage.Understand you can not eliminate all risk, only mitigate it.
