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.

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?

In terms of overheads, you should allow 5% of gross rents for vacancies, 5% for maintenance, $1550 for property taxes and $1000 if you want decent liability and wind/fire/theft insurance.Work backwards from there and you´ll have your bid price. 

I never said what criteria they didn't meet or where I got the info, the last thing I wanna do is tip these people off about how they use Facebook.I actually had one guy recently who's facebook profile pic was him giving two middle fingers to the camera while chillin with his pitbull, and online records showed 3 felonies including weapons, mob action, theft, and some other misdemeanor stuff.  

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.
