I wonder if there is an inexpensive way to protect the portfolio from very rare occasions.

I still do on occasion.

I've used Fidelity National Title on a number of occasions and have never had any problems. 

I've driven through there on occasion and  always wanted to get a look at that park but end up feeling a bit nervous.A friend has a place in 60618 and we tried to look there but it's very pricey now. 

A local investor in Denver with whom I’ve spoken on a few occasions mentioned recently that he has three residential properties he wants to unload. 

I felt like I can't do that since i'm giving them 2 legal notices even on separate occasions, thought couldn't do that . 

I've leased on Christmas eve/day and new year's eve/day on multiple occasions over the last 5 years. 

Getting the license makes a lot of sense now.I will tell you that there has been a number of occasions where disclosures were not given to me, especially the Agency Disclosures.In fact, one Broker was representing both the Seller and myself just recently and I never received the Dual Agency Disclosure.Another problem I see is in the case of a building that I bought over 6 years ago which is past the Statue of Limitation for Real Estate lawsuits, the legal use of the property was mis-represented by ALL parties, including the Agent, the Broker, the Appraiser and the Attorneys.

I am not an accredited investor and have on a couple of occasions seen attractive deals I couldn't get into because the investors are only accepting accredited investors.

@Charles Kao It can be a blessing to have the "right" lawyer around, especially when you need them (or so I've been told on many occasions).
