I currently own one buy and hold rental property (in addition to my personal residence that I own) and I am pursuing my Real estate Associates License (taking the test the first week in July).

If I get lead tested and there are high levels, do I open myself up to exposure? 

It is really appreciated.Just as @Brian Burke said, I am finding out how hard it is to do due diligence on the institutional investor.The sponsor said that they have a long standing relationship with the institutional investor although it does not appear they have had to go through a downturn in a deal together, which in my view would be the big test.

The practice tests online from Pearson are extremely helpful in preparing for the exam.

There are also "reserve" requirements that pop up when you have multiple financed properties, which require a certain amount in your accounts AFTER closing,  that only get more intense the more properties you have.  

I finally passed my test (finally!)

I have conversations with investors all the time about the difference between their spreadsheet and an eye test.  

With the help of these forums, I built a model that sensitivity tests MAO as function of capital structure, DSCR constraints, and cash flow per door thresholds.

Real estate ownership is capital intensive and when a tenant has mortgages on their balance sheet it can really be a drag on expansion plans.  

It was pretty intense.
