It means no background or credit check and it is possible you are renting to someone with a totally false identity.

Comps are hard to come by - there is a sale for 60k, & another for 90k in 2014 for identical units on the same street, and a 2016 sale for same type of duplex at 130k on the same street so the price is reasonable especially for the market in 2017 for the area. 

When valuing commercial (multifamily) the formula is similar, but not identical to looking at single family.  

Please do not disclose anyone's personal identity. 

do you find it strange that year to year expenses are identical down to the last dollar though the inputs swung significantly year to year on some items?

As you probably guessed, the result is nearly identical: you end up with about $250K in 30 years. 

But, truthfully, if you bought in Brooklyn and live in one half of a duplex, you'd still be subject to some CG because you rented the other half - they're two living spaces, so the portion of the your profit attributable to the rental space (half, assuming both sides are identical) would still be subject to CG.

The houses are identical expect for the fact that ours is a lot nicer and completely rehabbed.Here are the numbers:Purchase price: $160,000Mortgage: $1030 (taxes and insurance included)Proposed rent: $1,500Property management fees (10%): $150Cash Flow: $320 (max) - The house was completely rehabbed when we bought it so there should not be any major expenses, but I would still plan on setting aside at least $150 for small expenses/vacancies.My thought is this: Even if I broke even or made a hundred bucks or so a month, its better than taking a $10,000 hit, right?

An identical floor plan & SF, 2 BR condo can vary $50k where I live depending on the upgrades (original or upgraded kitchen, baths, floors?)

Your initial cash outlay will be identical since you're putting 25% down - hence your cash on cash return will look much better with the 30 year mortgage.If your goal is to maximize immediate cash flow there are several local banks that will offer a 24 month IO period AND 25 year am (fixed 5 yrs).If you're looking for a stable long term product - a conventional mortgage may be the best play.
