I'm a contractor at a medical clinic, and don't get any of the perks like the employees do. 

They've been very slow to respond to things that are not arguably directly health or safety issues, but this house is falling apart.

Hi @Dane MacLeod, Usually at the level of doing hundreds of homes business owners are using a mix of both the personal credit and the health of the business. 

Gavin Newsom, began in March with a goal of providing temporary housing for the 15,000 people in LAHSA’s records who were 65 or older or had chronic health conditions, most susceptible to Covid-19.

That way I could easily see profits per unit and admin expenses/total business health all in one place while still keeping all of my documents, tenant leasing and contact history, etc. right now I am just too spread out using Quicken, Tellus, Evernote for document storage (receipts, bills, quotes, etc), and OneNote for process/procedure documentation (my eMyth planning In Progress).

If you determine you have legal standing to refuse, I would recommend being completely honest with these guests that you have a legitimate health concern due to your daughter's allergies, and hopefully they will be understanding and the dog can stay at home.  

I need to get in there and renovate because there are some health concerns (mold).

Sometimes bad things hit good people.You never know, perhaps he has:Covid, orLost everything, orBecome deceased, orBeen diagnosed with a major health problem, orBeen served with divorce, orBeen arrested for drunk driving, oretc...; orJust decided he doesn't like you--for whatever reason.I knew a very well to do man who fell off the radar years ago when the economy took a nosedive.

My reason for making this post is to see advice from anybody else with a demanding health condition.

It is difficult for me, however, to understand her claims that her health is being adversely affected by living in a home that I know was clean and ready for a new tenant and I never was informed otherwise.I don't want to keep her as a tenant if she proves to be a difficult tenant.
