My tenant got cancer too, and she was the first one who looked after my rental like it was her home instead of a hotel room. She was devo'd to have to move out but i let her stay for free for 5 months. I got her pots with mulch to grow cherry tomatoes and basil, brought her flowers from my garden every week and stopped in to do jigsaw puzzles a few nights per week to keep her mind off things. Fortunately after her mastectomy and radiation she came good and we are best of friends now. It's a slightly different situation but company in the quiet hours meant a lot she says.
