In fact the manufacture of this technology have been in law suits because of issues with this lock.

However as real estate investors, we must also be concerned with liability and preventing lawsuits.

This protects you from frivolous lawsuits but also keeps you on track as a landlord.  

This is to project you from any law suits as well as tax benefits.

Hi, not sure about your budget however looking for a duplex/multifamily property, a home with an in-law suite, or a basement finished or one you can finish that could be used as more of a private suite would be beneficial.

The cash value attracts law suites regardless of how many properties.

If you want to do your own repairs, that is up to you but generally speaking, don't worry about having a lawsuit issue unless you are doing something really wrong.

I use a PO box here in Ohio, but my LLCs have to have a published address where service can be accepted (eg a process server for a lawsuit or whatever) and a post office box can't be served.  

What really matters is title, code or health violations, lawsuits, back taxes and liens.

The IRS lien has to be recorded or the United States of America listed as a co-defendant in the lawsuit for them to have the 120 day Right of Redemption.You also have to learn which liens have priority and super priority.
