Being a woman that is licensed in construction, still most times when people talk to us on business, they assume that my husband or son are  the ones they need to speak too.

I understand in the current political climate this kind of bigoted and hateful rhetoric is seen as cute by some but Iḿ not one of them.

who cares if it's 90% man or woman.

You need to look at the pet owner as much if not more than the pet, what experience do they have as an owner, do they really know much about the breed or did they get it just thinking it was cute or that they have some macho personality thing a guard dog is just cool?

I don't play with hard money, blanket, cute, commercial or car loans, so I'm enjoying this time with my family. 

During this time, I had received many inquiries, and had another woman fill out an application in which she completed within the day.

I once had a woman try to come to lease signing without all the money.. she said “you know where I work, it’s no worries”.

However; when Legal Aid sets this woman straight regarding owed rent dates she may pay on the 17th and then "get her act" together.The fault lies with the previous landlord (I'm guessing) who let these tenants slide regarding rent payments.Now with this business of terminating her lease. 

On the other hand, I bought a 5 plex a couple years ago and kept a elderly woman at 83 and kept her rent below market as I felt sorry for her and her place was in perfect shape.

I hate to make this comparison but your tenant sounds like my puppy except maybe she is not so cute.
