How to get comps on multi-family

[Andrew Jones]

Hi, BP community! I'm a new investor looking for my first deal. My current plan is to use the brrrr strategy on a multi-family with the intention to house hack. I was looking at a triplex recently and could only find single family units for comps, however some of them were similar in size and bedroom count. I was able to find a few smaller duplexes a little further away, but the neighborhoods were a little worse. 

Does being a multi-family add any value to the property or should I assume the value would be about the same as a similar sized single family?
