I currently work in the laboratory of one of the major hospitals in LA.My aims with real estate are to supplement my income through investing in buy to hold properties (SFH and multi family).

Professionally, I am laboratory technician for a biomedical facility.My goals are to start off wholesaling properties until I build enough capital to fix and flip.

Asbestos floor tile is not.Asbestos-containing ceiling tiles, floor tiles, undamaged laboratory cabinet tops, shingles, fire doors, siding shingles, etc. will not release asbestos fibers unless they are disturbed or damaged in some way.Asbestos pipe and boiler insulation does not present a hazard unless the protective canvas covering is cut or damaged in such a way that the asbestos underneath is actually exposed to the air.

@Jon Klaus We provide architecture and security services to folks building software (code audits, designing for fault tolerance and redundancy), mostly in the communications  sector.We also have a couple of our own in house software projects ... one of which is/was responsible for our move into real estate investing (we needed a live laboratory).

At night I'm a histology technician that works in a histopathology laboratory :)

Every deal is an experiment is the great laboratory called investing.What I appreciate the most from your post is the apparent willingness to learn from the exoerience. 

But I am actually full time Medical Laboratory Technologist.  

The following services are included: A physical walkthrough of the building to evaluate the potential presence of mold; Collection of tape lift samples of suspect mold and/or collection of air samples indoors and outdoors using slit-impactor Zefon cassettes, then submission of those samples for laboratory analysis; Temperature and humidity testing; Moisture testing using an infrared camera and pin-contact moisture meter; Collection of bulk asbestos survey samples of suspect materials which the consultant  feels will need to be disturbed to perform mold remediation work ;Testing of paint (per-1978 buildings only) and ceramic tile which the consultant feels will need to be disturbed to perform mold remediation work with an X-Ray Fluorescence machine; Photographs of the subject property and of situations or materials of note with regard to mold; Preparation of a formal report containing photographs, conclusions, recommendations, and laboratory report(s).

I also tried to arrange a trip into some of the laboratories in the old mine, but my contact was on vacation, so it did not happen.There are a few other Canadians here who invest in the U.S.A. and there are a fair number of past posts on the matter.  

Perhaps the most comprehensive study was done by the Appraisal Institute and the Lawrence Berkeley National Laboratory (although it's a little bit dated now, having been most recently updated in 2015 I believe).
