Have the house tested, and then abated if the walls do contain lead paint?

I've conducted two experiments over the last year with mixed results in order to test a couple of things.  

If it actually worked and simplified my life, I'd pay $50-$100 per property per month for it.If y'all are testing the waters, I'd recommend the following,1.

Perhaps you need to increase your income to more than 3x the rent or look for a less expensive unit where your income meets the 3x the rent test. 

They tested for a commode leak with green food coloring.

My lease has been fully reviewed by my attorney (Lowther-Johnson and Associates) and tested (I have won over a dozen money judgments, lost zero).  

You should run this test ad during due diligence.

I want to pass the license test the first time so I really need a good program!

And that certain tenant might trash your place/sell drugs/throw parties.

My current tenant got an inspector to take multiple samples of asbestos.The biggest asbestos items are in the attic.Popcorn ceiling everywhere, tested at 1% asbestos.In your experience, does having asbestos in the house make it more difficult to rent out?
