Typically, a lease should state that there is "joint and several liability in the case of multiple Tenants."

This puts me way above FHA limits for a duplex with a $310k purchase price.I am very happy that I learned this before putting up consultant fees and earnest money.

Someone could buy on contract and run down business, create further potential environmental liabilities, fail to make payments, and the market could decline.

I was planning on having the tenants get a renter's policy with 300k liability and name me as also insured, but I am not sure this enough. 

Our contract places a $500 limit on unauthorized expenses unless it's an emergency.

Of course this is ‘not guaranteed’ but reasonably safe to protect yourself against liability lawsuits.

However, I am a member of several different companies organized as Limited Liability Companies (LLCs) where members invest in a project (Single Purpose Entity) or projects (like a real estate LTH company) jointly, similar to (but different than) what you may see in a syndication or investment club investment.

By moving property to the spouse of a high-risk professional, it makes certain assets off limits.

A commercial broker seems like maybe an option but I believe they are limited to the state in which they operate?

I am just starting to learn about syndications and the concept of limited partners with a preferred return.
