You can have an environmental assessment done to determine if there is any contamination.

Assessed tax value $169k, Zestimate, always questionable, $181k.

Is the 175K a solid comp (at the lower end)?  

Also, being a firefighter, I could accurately assess how specifically the fire damaged the structural elements.  

Or would it be cheaper, from a tax assessment perspective, if I kept them separate?

Agree on assessment of #4.

You haven't provided enough details to allow for a proper assessment of value.

,Your assessment of the benefits and drawbacks of our model are spot on!

I'm trying to assess if this is something that I want to get tangled up in.As far as the neighborhood, I've ascertained of the 10 lots/properties (all homes are built circa 1959) there are 7 OO.

I also look at the active and pending listings as well in order to gauge what people think they can sell for and to assess the competition.
