Don't purchase anything older than a home built from June 15,, 1976 or before and even then be very careful about investing in any MH built in even the late 70's as many used a number of caustic (formaldehyde) and carcinogenic (asbestos) chemicals and substances until the laws changed in '79-'80.Additionally, if the home has ever been moved from it's original situs (one site to another except from the manufacturers and/or dealers retail lot) as conventional financing would be very difficult to come by.

You need chemicals and traps.

Personally, Chemical Bank has been helpful to me when purchasing my duplex. 

I even have my equipment to spray bathtubs, cabinets, tile, countertops and the chemical supplier in my contact list. 

As an example, I just found out that there are a few plants around where I live that are omitting very harmful chemicals.

Be careful about selecting used units as they are frequently spayed with pesticides especially on the floor area and these chemicals can be harmful to human beings who are exposed to them long term.

Hello BP Community,I was wondering if anyone has experience in their full time job (if it is not flipping houses) that directly translates or contributes to contractor/project management as it relates to flipping houses.For example, I am a new investor working full time as a chemical engineer.

Sometimes it just comes down to cost.There are two choices, sand or chemically strip.

They make a chemical that will help remove it not always a complete fix. 

At this location they also had a lot of screws/nails and a lot of light bulbs and lawn care chemicals.
