It is certainly not impossible but the opportunities are few and far between in my experience.

Amazingly, it is apparently nearly impossible to get decent comps for this so I'm not sure how to approach figuring out whether to outright sell it (and for what price), fix it up as a rental, or market it as a knockdown for the land. 

It's impossible to paint each situation with a broad brush because it truly is case by case given the work that was done, inspector that is handling it, etc.

Chrome on mobile is clunky enough but BP banners, ads and layouts make it almost impossible to see what I type, answer questions etc.

Not to be dismissive, but it is almost impossible to answer that question without first understanding what your goals are. 

It will make things pretty tricky but not necessarily impossible.

Which in many markets with todays interest rates is all but impossible.

I don't want to offend anyone or give them some sort of impossible criteria from their point of view. 

The costs of land  , engineering , site work , permits , labor , and building materials make this virtually impossible . then there are zoning issues and the rest of the politics that go along with this . 

Today it's simply impossible.
