The owner is elderly and is in failing health.

Especially if the landlord is/was elderly...

Also not to stereotype but can't tell you how often we go into homes with elderly tenants where they have no idea the place smells.

And give a little background.I helped my elderly parents manage their rentals for many years, but they were all sold after my mother passed away 3 years ago so the assets could be split between 11 heirs.  

Basically, the IRS was trying to collect from a divorced elderly woman the debt based on the joint returns she filed with her ex-husband.

However, the seller is an elderly woman with significant health issues who lives in another state and is non-responsive to her listing agent. 

And with a ROW home, it may not be so much the noise and the shaking sensation for an elderly person with health issues. 

One of the tenants is an elderly woman, 76 years old, who does have limitations in regards to her activities of daily living.

Aloha,First off, 1 - 3 days "after grace period" most certainly IS late (excluding weekends and holidays). and you should confirm with prior LL that they paid the "late fee".Second, by offering lower rent to someone with apparently good records, vs. what I am assuming is market rent to the person with poor history AND an elderly, disabled person is exactly what can get you into a Fair Housing violation.

The house and large detachable garage are in rough shape, the landscaping is grossly overgrown, and the lady is a an elderly horder, with potential financial problems, who is stuck in her ways.My neighbor/realtor briefly talked to her and was turned away as far as her wanting to sell.
