It seems everyone is going over or under this size of multi families.

That company (let's call the company and the contact there MW) seemed to wholesale the property, had contractors to help flip the house (that needed a full gut) and was originally going to serve as my property managers.

I served 21 years and wish I would have kept my houses each time I moved.Brandon has a good book on managing rentals.

I don't know your market but in the Quad Cities, a 7.5% cap rate is pretty typical for small and medium sized apartments. 

That’s why I have a minimum note size of $400,000 that I will invest in, and I prefer $1 - $4 million.On another but related topic, I have owned, or my company has owned over 650 notes over the last 20 years.

Older double-wide mobile on nearly 6 acres of land that is mostly forested and amongst 9 other properties about the same size.

A key factor is going to be whether or not your window sizes are standard or not.

You can also look up median rents in any city with census data but I believe that is a inclusive of all housing types, sizes, bedroom/bathrooms, etc. so I wouldn’t use that to analyze a specific deal but not a bad option when analyzing markets. 

If you don’t have a lot of experience or first time doing one this size I’d bring it help so you aren’t missing anything.

After serving 20+ years in the military, this really resonates with me.
