For the duplex, would you consider it to be in a high quality (A), medium (B), or low (C) neighborhood?

My clients can "force appreciate" the value of the property by doing a quality rehab for a lower than market cost because they are very good at spotting "diamonds in the rough".

Well-maintained homes: Homeowners tend to spend more time and money maintaining their homes, which contributes to the overall quality of the neighborhood.

@Chris Kay finding a quality, cost-effective contractor is extremely difficult:(There are thousands of contractors that are great talkers, but rarely perform within budget.Standard bait & switch is to lowball a bid, then once they get started all sorts of things "pop up" that somehow their bid didn't cover.
