AQ Testing Services - Linda Lauver - 440 Cobia Dr in Katy for TESTINGPuroClean for RemediationI haven't used either, but people I trust in my office recommend both.Hope this helps!

If you're on site "managing" contractors, but you're really watching TV, playing on your phone and sipping your favorite libation the majority of the time, while intermittently talking to the contractors and checking their work, well that won't help your case.We frequently use the primary purpose test here. 

@Giovanni Cardenas I found that taking as many practice tests for the exam as possible was helpful.

Test the waters, take action and adjust along the way!

Regarding your goals, a SFR is a great way to test waters on being a landlord.  

Stress test your analysis to ensure you can make it through any potential pull back in the market.

Also, if you are buying a 3-4 unit property, make sure you educate yourself on the Self Sufficiency test (aka Stress Test) that FHA requires. 

Before contacting people in the markets we are looking at and trying to build a team (as David Greene suggests in his podcasts and book) we started doing "test" analysis of different neighborhoods and areas in these markets.  

I believe this has the same effect as test driving the car you like at the dealership.

TenantCloud is one I've tested.
