I have the opportunity to buy a house that tested positive for meth in an inspection.

I stacked hay, drove tractor, balers, seeders, and other farm implements, broke horses, trained race horses, jockeyed, trimmed trees, shoveled snow, worked at several gas stations, painted houses, painted coal dredges, security guard, roto tilled yards, planted flowers and gardens for folks, raked leaves/yardwork, eventually worked oil field when it was booming, even crawled in tunnels installing coaxial cables and fiber optics, loaded explosives in seismic testing holes, eventually a lawyer, and landlord. 

Heat Lamps should be Ok, Most are on timers from pet stores which are tested and certified.

Google 'Howey Test' for a bit more information on determining if something is a securityhttps://consumer.findlaw.com/securities-law/what-is-the-howey-test.html

My capital is tied up in that home and I have a vacant property sitting there not being used and the demand for short term rentals decently high in this city, a concept tested by other 1bed/1bath small cottages.

The Memphis market is going thru an investor boom right now, so it is slim pickings here.

It took several hours for the test to be conducted as they test almost every surface in the house, soil and also the garage if you have one.

This also gives you a chance to get to know your market and also test out the management you decide to use without exposing yourself to the additional risks of rehab. 

If you have a house across town, and are only sleeping there a few nights a month to justify the FHA loan, and are using AriBNB to generate income, you are not likely to pass the sniff test.

But I am open to any advice, what books to read, maybe take an REA to lunch and pick their brain, what to do/how to prepare for the test, etc.
