If they look like fiberglass, it's a good idea to use a respirator, long sleeves, etc if you tear them out - just like dealing with fiberglass insulation. 

I have a few tricks up my sleeve, though... and am pretty sure that the bank will be buying this at the auction, and not a 3rd party.

That includes trenching for electrical lines, skim coating drywall, landscaping, and - yes - due diligence on new purchases.I don't know if that's a "mentor" or not, but I admire folks who roll up their sleeves and dive in.

It gets easier as you go, and the experience will help propel you.Be aware that rolling up your sleeves to do everything yourself can increase your initial equity position, but you have to have the time, capital, risk tolerance and resources to make that happen. 

Modern gas stoves and fireplace inserts are sealed (airtight) with respect to the living space (room) and vent their combustion air from outside - typically a separate pipe through the side of the building or a centre pipe within the exhaust flue (either through the side of the building or as a sleeve in an existing chimney.The cheapest way to stop air and heat from being drawn up your chimney is to decommission your fireplace; stuff insulation in the top of the firebox against the closed damper; then tape a sheet of 6mil poly (vapour barrier) under the insulation being certain to create a seal with the sides of the firebox all the way around the perimeter of the barrier.Since you still want to use your fireplace periodically, but do not wish to incur the expense of installing an airtight insert, you could still attempt to plug the top of the firebox when you are not using the fireplace.  

Meth leaves a chemical residue behind that will seep into walls, so you'll have to use something pretty strong, and wear respiratory and skin (gloves, sleeves and goggles) protection.

My demeanor, communication style and Carlton Sheets program that I spent $145 on and expect a ROI willingness to roll up sleeves for long hours of sweat equity are absolutely grounded in business ethos.

You could just be having an allergic reaction to the glue in the wallpaper, which would be an easier problem to solve - be sure to wear gloves and long sleeves.

Get some cool skills under your sleeves.

I had to roll up my sleeves and get to work.
