Meth test

[Willem Hendriks]

Im looking at buying my first duplex rental property. I had a meth test done in both units one at the furnace by the filter and at the return air duct in the other. Results showed .22 micrograms in the unit done at the furnace and the other unit done at the return air came back as 2.24 micrograms. Should this be a deal breaker? Im a newbie and dont know much about this any help would be greatly appreciated thanks.
