If it is super outdated with ugly colored fixtures, you may have a harder time selling it.

Maybe I can a screen shot of him trying to scam me and have him blocked on FB. 

We've brought in two dehumidifiers which are helping, but I'm not sure what the root problem is or even who to ask for help.One contractor said moisture is coming through a hole in the exterior stucco, but another said no way because the vapor barrier would block it. 1st one recommended installing insulation, but I've also read this can increase condensation problems.

There is a hill right next to it with million dollar homes and then two more blocks down a LOT of lower income apartments.

Flash forward 10 years and most every building block of a home re/construction seems around TWICE the price it was just a decade ago. 

In this case I'm a renter and my landlord is outright refusing to trim big palm trees (not those smaller ones, these are about 15-18ft tall) that have overgrown to partially block the driveway with its branches.

I know you're 100% right on neighborhoods, one block here can mean 50k or more!

Don't know that very many people are looking for a "nice" house on an "average" block.

If a meter is being blocked by a gate or a door then it must have an SDG&E approved lock installed, no exceptions.

Are you going with a significantly dissimilar, and/or lighter color?
