If I may ...
Whoaaaa! So, now, more information is divulged. From what I've surmised .... your "500 foot", $500,000 dollar run, (comprising electrical wiring, cable and telephone, buried underground), was not for a single family home, but for a multi-unit condo, aka, an apartment complex with individual space, unit, mortgages. The truest apple to oranges example as I've ever seen. Why don't you just shut the f-ck up. Or, if at all, compare apples to apples in your commentary from hence forth? So it begs the question, (I am not begging you). Why the fu-k would you attempt to equate a condo construction to the OP's question?
