In order to get the terms I want, would it make sense to offer a premium on the purchase price ($3.1 million instead of the $3 million FMV)? 

howdy BP'erswe have a house we are rehabbing (flipping) in Denver that has two fireplaces, the upstairs has a working gas log set up from the 50's, cute but probably not terribly efficient. the basement has a fireplace with a gas pipe stubbed to the fireplace that is currently a wood fireplace. we are thinking of keeping the downstairs FP as wood burning. the question is what to put in the upstairs fireplace. tell us your thoughts:gas insert ?

It's almost shouting for a 10 year old to think it would be a cool place to play, fall through the wood, and break a leg. 

Unless the fire stopped on its own, there was a heavy amount of water being sprayed into the home and that brings additional damages & hazards that you need to be aware of (wood rot, mold, etc.)

Thanks for the reply @Mike Wood.

The problems came with these when they were insulated and skirted causing moisture to get inside the cavity and rot the wood and keep the insulation damp.

I could tell which boards were the original treated Exotic wood ($800) per sheet and which were regular marine plywood.

Blonde wood, perhaps?

I never buy wood or manufactured houses.

The paint on the trim was also not primed first so some of the wood was showing through.
