Buying multi unit homes!

[Cody Wojasinski]

Not sure if this is the best place for it. I'm currently saving money for a down payment on a rental property and while I do my research on deals and homes I and across a 4 unit multi family for 90k with tenants. All of which are 1bd 1bath units. How easy is it to fill I bedroom units vice say a unit that can accommodate an entire family? Just looking on any ones advice about multi family homes ect. I've also found some 2bd 2.5 bath multi family homes in a college town for 185k. Just not sure what I should aim for.
