To me they are either liability or headaches.Should I let the demolition crew take them in exchange for a price reduction?

Putting the proper weight on each indicator is critical and comes down to skill and experience. 

If my property is a piece of shined up you know what, I'm going to pay in the form of net proceeds reduction but, if my property looks the same, is in the same condition and has the same characteristics as every other home on the open market, mine is going to sell at the same price the other ones are going to sell it.

Good ones (any vendor) are worth their weight in gold.

Hi anthony, that is pretty incredible, way to maximize space, i would be careful about your weight though, some companies will charge you if that dumpster is over weight even though you wont know how much it weighs, but non the less that is some meticulous stacking, Props!

Sharp professionals can be hard to find but are worth their weight in gold.BPers are kinda down on paid education, but it works for me.

I don't know much about ensemble methods, and that's the only reason I haven't tried them yet. ...although I may already be doing something similar: I typically average the results of 30 or so NNs (same architecture but initialized with different weights) to give me a prediction.

A quality PM will make/save you far more than they ever charge you in fees and although your individual experience might have been negative I can assure you that true professional PM's are worth their weight in gold. 

With the reduction in number of San Diego rental units driving up the demand on my Escondido units, I would raise rents of all Escondido units.
