Single Family? 

I actually think you need to commit to a type of renter or the murphy gives you flexibility for a smaller family. just a jumble of thoughts on the topic.   

Based on the conversation my realtor had with the seller's agent, the family selling the home is humanitarian in nature and would like to "help a family."

Thanks @Johnny MartinMy suggestion is to partner with a like minded person... and preferably someone like a family member who really knows you... a dad... an uncle, etc that understands the value of passive investing.
