Struggling between 2 rental applicants

[Mike H.]

We own 2 duplexes and have been landlords since 2009.  We are just completing a major renovation of our second duplex, which we picked up at auction in the fall.  We have executed leases and secured deposits on one of the units, and have 2 strong applications in hand for the last remaining unit.  We are struggling to decide between the two sets of applications and could use some feedback.

Both applicants are married couples.  Couple A has two incomes, a W2 employee and a self-employed person, and they live in our area.  Couple B has 1 income presently, but are relocating to the area and would have 2 incomes shortly.  Couple A has seen the property 3 times in 3 days, and have seemed lukewarm to our property for a while before coming on strong as of late.  Couple B walked into the property today and said "we'll take it" within 5 minutes.  Couple A's and Couple B's credit scores are within 10 points of each others, essentially identical.  Couple A has asked us to provide a storage shed for the back yard which would add approximately $500-$1,000 in expenses, and have asked other questions that lead us to believe they may a little "particular".  Couple B seems content with the property as is.  Couple A submitted their application 12 hours before Couple B, but were told we would evaluate after reviewing all applications.  We have yet to check landlord references, but have verified income.

I am looking for some feedback from experienced landlords as to who they would select.  We can make a compelling case for each.  Couple A's dual incomes may outweigh their extraordinary amount of questions and request for the shed, etc.  Couple B's lack of a dual income may be outweighed by their very easygoing demeanor.  The credit history seems to be a non factor with each.  What would you do?
