So during the time that I was waiting to close of the property, I was reading some stories and ran into one about termites and they showed pics of what termites look like and how to detect them.

No way to know for sure short of your agent doing some detective work and just calling the listing agent.

You could also have water sensors, either to detect excessive water usage (such as leaking supply line), or water on the floor (next to a water heater, or on a lower level, etc.).

On your first deal you won't be very good at any of them - negotiating, knowing your rehab budget, ARV, timing, holding costs, how to detect "surprises", etc. 

I called a local plumber to perform a leak detection test and found no leaks.

To find them partly it is your own detective work.

You'll have to do some detective work.

Best to get a plumber to do leak detection.

However, all successful investors learns to differentiate fantasy from reality and the way to do this is to start with your real estate education.Reading and posting on discussion forums will not teach you the fundamentals of dealmaking, let alone become a true opportunity detective.

@Nicolas PaezThanks for the great tips, will have to do a little more detective work.
