getting ready for first eviction, sort of. Need advice

[Rodney Morris]

background:

We are new to land-lording and I had to make some concessions to get my wife on-board. the first property we put out was offered to a friend of hers (side note; I hate dealing with friends and family so i was against this from the beginning) and has been a PITA since. We (my wife) gave her a date and she kept asking when she could move in. So i gave her a date and told her she needed to give us the deposit and first months' rent. She and my wife met and she gave the full deposit and 1/3 of the first month's rent saying she got paid in a week and would give the rest then. My wife accepted, since they are friends, and told her she cannot move in until the remainder was paid.  the rest was due on 08/08 and hasn't been paid yet. she says she isnt staying there and i work shift work so i cannot do a stakeout right now. I have offered and prefer to accept automatic bank drafts and she said she was interested but has not signed up. We also just found out she no longer works at the place she did when we made the agreements. Not sure if she is employed at all.

I know i am going to blasted here so i may as well tell you now. She did sign a M2M lease but my wife opted to not do a background and credit check. I'm sure many of you are going to say i deserve what i get, and i agree.

my questions: 1- since she has not paid the entire first months rent and we have in writing she can't move in until she does has she technically established tenancy? 2 - if she pays before the end of the grace period should we still need to do an eviction? 3 - if she pays and the wife agrees to let her stay is it too late to make her complete the background and credit check before we renew the M2M?

Any other advice for this situation would be greatly appreciated.
