I then adjust it if the house is superior or inferior to the majority of houses in the given market. 

.* Look at recent sales of ANY duplexes in the area and adjust for differences (older built, inferior quality/condition/location, gla, bedroom/bathroom, etc)* Look at recent sales in other neighborhoods and adjust for differences, including neighborhood differences (Yours might be in a better Nhbd or worse, etc)We would also to a cost approach.

I have mastered every single criteria needed to wholesale, and that is why I am not king of the mountain in CT, while all the nay sayers here, still argue amongst themselves how wholesaling is inferior. ;)

Light Rail + PATH is in my mind dramatically inferior for anything say north of 34th Street in Manhattan, and even for lower streets closer to Midtown bus + subway seem to be at par.My take is taking the bus where the distance to the city is short enough (such as from near 30th street in Union City, or most places in Weehawken) works very well even if adjusting for any volatility/absolute deviation due to traffic.There is a psychological barrier with buses, where the latter are perceived to be significantly volatile vs subways, though I have observed decent volatility with subways as well. 

Some state's liens will even take precedence over federal tax liens.In a tax sale situation I would check at the county clerk's office (which in some areas is online) for any tax liens filed against the owner of the property.In a normal foreclosure situation (for a mortgage lien), the foreclosure will wipe out all inferior liens that are not for city assessments, county taxes, state taxes, or federal taxes.

Gas stoves are far inferior compared to induction stoves.

In my opinion they are neither superior nor inferior to stocks and they have their own unique pros and cons.

They use pure price per square foot comps not accounting for inferior location, smaller lot size, obsolete layout, or non optimal room size/bedroom count. 

I bought a brick building built in the late 1800's and a lot of the design and construction was vastly inferior to what you would find today.
