Please respond if you have any ideas or suggestions on how to deal with this situation or what I can say to express to the tenant in a kind way (if at all possible) to be courteous of your neighbors especially in the middle of the night and that I can hear everything so it would be great if she could keep it down.I am looking for solutions, not sarcasm.Thanks for your time.

Tenant expressed that it will be difficult for her to pay the whole rent if her daughter/son in law move out. ( they are not 100% sure if they are moving in August/2015).The tenant is letting me know as a courtesy.

Talk with her in person if you can so you hear not only her words, phrasing and tone of voice, but so you can also see the non-verbal communication in her facial expression and body language.

Our current tenant loves the place and has expressed her intentions to stay there long term.We have since replaced an LED light fixture due to factory defect and had a maintenance call from the new tenant.  

Me I would send a PDF version of the document with his information already entered  (after the background/credit check)  and ask him to scan signed version to you and  express mail the original with the checks. 

Landlord makes no express or implied warranties as to the Property's condition.- Please list in the application any applicant request for landlord to consider regarding repairs or treatments should applicant and landlord enter into a lease.

I finally agreed to give her "first right of refusal" through 10AM the next morning, ie, would call her to book if someone else expressed interest.I woke up the next morning to several voice mails from different people expressing interest, so I called her back to see if she was ready to book now. 

Pricing is pretty low compared to what the market will bear (pardon the vagueness of the expression lol).

Occasionally I drive by a property and, because it looks like it has some deferred maintenance, I'll consider selling the owner a letter expressing interest to purchase.  

Floating the payments a few days unless you pay for express payments.
