So if the land its not compromised, environmentally due to the plant, Its worth it.

It's tough to really compromise that and impossible to justify.

I like to find a compromise between finding properties that fit investor criteria at list price (high probability of accepted offer) and throwing out a ton of lowball offers (high probability of great deal if accepted).

By doing that, you have greatly compromised the structural integrity of the wall.

Rather than make ethical or legal compromises, you'd do better to accept it or try to change the system through political means. 

She agreed and said she'd talk to the folks about taking 5% down, but mentioned we may have to compromise on that.Re: interest rates, I didn't go into specifics but I mentioned that we could do something in the middle of what they could expect in CD's (a measly 1.5% if they're lucky) and what I would pay for a mortgage.

This often means compromise and understanding each other.

If you can do something like that, half a point isn't that bad a compromise in order to remove the uncertainty of the HELOC.

If you are going to be a landlord and have lease language you expect a tenant to follow there can be no compromise without rewriting your lease.

Likely you will have to compromise a bit because you need to create a win win for both parties involved.
