Rental versus flipping

[Jennifer MacDonald]

I have purchased a home that will be ready for either rental or for a flip and I am trying to decide what to do.    After purchase price and renovations minus closing cost I stand to make around $20,000 if I flip this property.  I will have held the property for 45 days at that point.  

Or I could rent this property with a cash flow of $400/month with a tenant that is interested in a lease to own scenario. 

Which would be the better deal?  Thank you in advance for your advice/help.
