@Victoria Winters I previously worked with a group that specialised in hotels at the higher end of the market where it is all about branding and bringing in the right clients.  

Can't wait to dive in, uncover knowledge and possibly meet some other realtors/investors.

Do people even test for it upon purchase inspection or do most not uncover a potential issue?

Even if you think a certain activity or group is pointless sometimes you will uncover $$ opportunities.

I think that is always recommended and it is something I do.My inspector has uncovered things they werent aware of and has also alerted me to issues to monitor to make sure they are rehabbed properly (for instance ensuring that the electrical scope included adding additional circuits because the current number was deficient).

A visual inspection and a pressure test should uncover most issues. 

At times, the seller may back out, we may uncover bad things about the property during the due diligence period which will cause us to back out of the deal, or financing may fall through.What makes it even worse, we, as investors, may incur some soft costs (costs incurred prior to closing) which end up being sunk costs.However, as investors, we are relentless in our pursuit of cash-flow.

Some of the details that investigators uncovered — escorts, Lakers-game tickets, clandestine meetings, and cover-ups — belong in the plot of a great noir (a genre that has fictionalized some of L.A.’s ugliest truths).

I had my home inspector inspect the property but with the power, water and gas shut off there wasn't too much he would've been able to uncover.

Or did you uncover a reason no one had snapped it up?
