Life if a repair isn't up to my standards, or he doesn't like taking directions from a woman.  

The tenant, temporarily now a single young woman, soon states that she is afraid to remain there and moves out.The interior of the house was always well kept and before moving out the tenant apparently  cleaned it well.  

I am married to a woman that has been saving money for about 25 years.  

I am a woman just starting my venture as a landlord.  

I am assuming you went out to a local car dealer ( whether new or used) - not knowing the salesman (or woman!)

I am a woman with a strong character and personality.  

I usually have the woman who does our family pictures take a few extras of just me each year to see if I can use one as a headshot.

Since you have some empathy for the woman's plight, I suggest you start by listing all of your concerns/lease violations in a written notice and give them a copy. 

I've got a couple decent candidates I'm considering, both with pros and cons...1st OPTION:Doctor + retired woman, both mid-60s, no kids, no pets~ 9x monthly rent in income2-year lease... potentially longer termGreat credit score-- However --Tax liens, bankruptcy, both have "messy" divorces in past couple yearsOnly been dating for about a yearDUI, expired plates, and another charge I'm looking into--2nd OPTION:Young couple, Dad + stay-at-home mom, baby, small dogRelocating from Texas~ 4x monthly rent in income1-year lease... almost guaranteed not longer than thatAlready had higher house payment in Texas, so rent would be cheaperExcellent credit scorePerfect background checkPerfect credit reportSo the question is, do you go with the older couple without the pet who's already interested in signing a 2-year lease and could potentially stay longer?

I have an advantage being a woman I think - I can ask "dumb" questions and the guys answer me - (no eye rolling) - but I make sure I learn whatever the lesson is - I'm "trainable".
