I am not licensed to practice in your state, but generally people have a duty to mitigate their damages.

I recently walked through a SFH that I am considering buying as a college student rental property, and I noticed that there is a radon mitigation system installed.

There is the customer service department, collections department, bankruptcy department, loss mitigation department, short sale department, foreclosure department, and on and on.

To mitigate these risks, cash out the deal ASAP to avoid having too much of your $$ tied up in the property without owning it outright. 

For example, Georgia is not tenant friendly and the LL does not have to mitigate damages if a tenant leaves early.

So, I guess my question, really, is how do I mitigate my risk?  

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.

My suggestion is to add at least 25% to the cost of the foundation repair as mitigation to the problems that will come from the foundation repair.If anyone has more experience with any of these, please correct me if mistaken.A rule of thumb for a "quick and dirty" foundation estimate without engaging a foundation contractor...yet.

You can mitigate this and be different (instead of the endless stream of newbies who come on BP, post once and then disappear) by educating yourself ahead of time, maybe doing a deal on your own etc.I have been doing this for 3 years.

It's also a lot more risky if the market falls you will be upside down where as normally mortgage paydown mitigates this.
