., @Brian Freeman , @Colin Zhu, @Ross Denman, @Todd Burton and many others who provided insider knowledge about the same scam, undoubtedly preventing many more people from being scammed by coming public with what they knew@Dave Foster for answering my 1031 questions@Chris Lopez for all things Denver-related@Russell Brazil for dropping lots of solid knowledge about being an RE agent (btw do you have solar panels on your roof yet?)

I will be doing some extensive work and not much of the old will remain.I have several alternatives that I'm looking at radiant floor heating, electric heat pump with gas furnace, geothermal heat pump and solar panels to supplement electric or gas heat.I would welcome other ideas, thoughts, pros, cons, etc.

Either way, sheet vinyl in the kitchen and baths and all that dark paneling gets primed and painted.  

The issue is exacerbated with the leased panels over the purchased ones as well.

Open the front panel and check filter to see how it's maintained.  

Water heater had issues too, and no electrical panel in the basement, and the vent for the microwave or lack thereof would be an issue, no guard rails, ALL KINDS of issues.

The other option is Structural Insulated Panels (SIPS) but that is for another thread. 

Likeplumbing not up to code - improper venting, wrong pipes or sizes used, galvanized pipe, copper pipe in slab etc.undersized framing, spans to long, dry rot, termite damagefoundation cracks, settlement, sill plates rottingasbestos in tiles, plaster, popcorn ceilings, pipe wraps, vent wraps, old furnace insulation. electrical grounds missing or improper, overloaded circuits, old panel, undersized panel, outlets not to code, aluminum wire, nob and tube wiremold in crawlspaces, basement, atticbad drainage in yard, water intrusion spots on house and foundation.oil tank in ground, radon testThese are just a very few things that you may not pick up if you don't know what to look for.And as previous said any findings are used to negotiate on price and/or save you from a big ticket item like asbestos removal, structure, water problems etc.

On assembly though, i always used an adhesive glue (eg liquid nails) on panels assembled together.

I do try and take a lot of pictures and make sure to take pictures of mechanical equipment, water tank, and electrical panel!
