I know that for an investment property on a small multi-family home you need at least 25% of the purchase price down if you are not going to occupy the property. 

Hey BP Community,I'll be closing on my 5th single family home investment property in a few weeks.

Main point of my post is also trying to determine if individual notes are worth it for people in my boat, who are busy and happy with other aspects of their lives... jobs, families, etc.

@Jorge Abreu I myself do not invest in large multi-family properties as of now.

I say “currently” because there is a bill passing through the legislature even as we speak to remove that requirement for 3-4 unit properties, so patience might be rewarded.And just make sure the zoning allows 3-families before you make a decision based on that potential.  

Multiple studies show that these families typically have no ability to cover a $400 emergency.

I know that in single families in Cleveland Heights people have put in basement bedrooms with an egress window and they were on formal plans that were submitted to the city and approved.
