While they *should* I've seen plenty of streets of identical duplexes that don't really age the same.

And if you look at the industry distribution of the labor force in terms of industry they work in, the County of LA percentages is almost identical to the national numbers.

To illustrate what I mean, take 2 identical 1200 SF homes, the only difference is one is located in Phoenix and it rents for $1200/mo while the other is in Los Angeles so it rents for $3000/mo. 50% rule predicts that the operating expenses for the Phoenix house will be $600/mo and the expenses for the LA house will be $1500/mo ...

Hey Everybody,So I'm thinking about buying a quadplex that's on a street with eight almost identical quads on each side of the street total.

Sorry everyone, my bigger pockets app kept crashing and now I notice there are two identical posts.

@Johann Jells As a MA notary, I'm assuming that NJ laws are the same - they may not be.One of the notary's primary functions is to verify that the person signing a document has presented evidence of their identity. 

His unit is currently sitting at $375, while the other two identical units which have turned over more frequently are renting for $400 and $425.

@Chris Nance @Stefanie Jensenhttps://www.biggerpockets.com/forums/12/topics/490545-i-want-to-buy-a-rental-now-my-husband-wants-to-wait-a-seeChrisThe above link to another earlier post " I want to buy, but my husband wants to wait and see".Almost identical to your situation but other way round.

You can have TWO identical 8 unit properties side-by-side and one has a NOI of $25,000 and another at $32,000.

Nothing is identical and the fact that your own situation is constantly changing depending on where and what your invested into makes it hard to have a checklist that others would find useful.
