Help with comping a property please!

[Miguel Hernandez]

Hello BP members. I am in need of some assistance. I am planning to purchase a 3bed 2bath duplex in my market. However, when I run comps I am pulling lots of single family homes. Single family homes seem to have a higher ARV than a multi family. Am I able to still use the single family homes as comps if they have the same square feet, bedrooms, baths, etc?

Also my main goal is monthly cash flow. If I keep the property as a duplex I will receive more in monthly cash flow, but if I tear down a wall and connect the units the ARV will be higher, I just won't cash flow as much. Any help on what the smarter move here is? Thank you any help is appreciated.
