They both may be viable alternatives for a buyer in that market area, hence they may both be comps.So, the appraiser may've used more similar comps in different zip codes, then dissimilar comps from the same zip code, but they may all be in the same market area.And if you are saying the same subdivision has properties in different zip codes, then it may well be that the comps in the same subdivision are more comparable than the comps in a different subdivision, irrespective of their zip codes.

@Scott E. super bummed you had a bad experience here in Tucson however sounds like you had an experience that was not that dissimilar to my impressions of Central Phoenix which is a VERY different area versus where you live in Scottsdale (a suburb of Phoenix).

There is actually another device you can use instead of a keyless deadbolt.

I have found a couple of devices which seem to do the job:https://www.amazon.com/bluebot-Universal-Detection-Tracking-Required/dp/B08V9DKFR3/ref=psdc_3180231_t1_B08DX6MP8X https://www.amazon.com/Moen-900-001-4-Inch-Smart-Shutoff/dp/B00C03D01QInstalling multiple meters is a non-starter due to the price. 

Turnkey property, new carpet, good condition devices, freshly painted.

Rehabbers often upgrade electrical service because homeowners these days tend to have more spaces, some very high wattage appliances, more devices, etc.  10% for GC overhead is reasonable, assuming the GC isn't getting overcharged by his subs.

There are certain tricks to getting approved for high credit lines such as applying for the right credit cards in the right order or I have even heard of people having multiple card applications open on different devices and clicking apply at the same time on all of them.

Rather than debating three versus eight, do you concur or disagree that a decentralized grid system of micro-production and storage through household systems including storage in EVs would reduce the vulnerability for millions of people to an event such as a localised EMP device or hack, versus a centralised grid servicing millionsIt's my belief that the huge push towards EVs, autonomous vehicles and in part the progress in PV solar and storage is all interconnected to a desire at a corporate level to develop software and systems that will run "Grid 2.0".
