You answered because its a comparable which didn't make sense to me so I asked a follow-up question trying to get to the root of why the builder needs to lower the asking price.  

We would try to save the tenancy by addressing the root cause of the problem, but if we couldn't, then we would do what we can to mutually agree with the tenant to end the tenancy.

I think it would be important to understand why the rents have been decreasing, and if that root cause will apply to your property.

I'll be rooting for your turn this coming December 😀

I am familiar with the area, and I think it will take some time for changes to take root.

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.

How do you prevent huge dental bills and root canals?

Did tree roots break apart the clay pipe?

The hillbilly roots I have are itching for a conflict. 

But the first thing is to determine the root cause of the building's current occupancy status.
