Residential or Commercial Loan?

[Nicholas Gessner]

I recently came across an MLS listing for a duplex @ $100k. In the description it states that buyers can purchase the one duplex or all 8 of the current investor's duplexs on the same street for an $80,000 discount, Or $720k. It seems interesting and was wondering would this require 8 different residential loans or a commercial loan for all 8? Still new to investing so was curious because I have seen several different package deals when looking around.
