Tenant wants to modify unit? Thoughts?

[Kate Gagnon]

Hi Folks,

I just was curious what other people would do. I have a long term tenant in a duplex. I have let her paint her walls and when she wanted to upgrade ceiling fixtures, I had them installed for her and she paid for the fixtures. 

Currently her daughter wants to pay to have her linoleum floor upgraded to tile, and she has asked if this is OK. My thoughts are do I allow the upgrade with the condition that I approve the materials and contractor OR just say no? 

What is everyone's thoughts?
