Quadplex in Cleveland - I need some real advice. Thanks!

[Samme Chan]

Hello. I'm looking into a real estate investing in the Cleveland and Akron area. There's been some quadplex homes that I'm interested in. What are the pros and cons of owning a quadplex vs. duplex? Would you recommend buying it with cash? They are fully tenant occupied. The buildings are not renovated, but they seem like they're in okay condition from the pictures. Are there any building regulations for quadplex that are more complicated compared to duplexes? Any advice are welcome, even if they have nothing to do with what I'm asking! Thank you all!
