Your health and well being is worth more and if she doesn't care, then that is your answer.

Hey Will,As a PM in the area:-have a lawyer look over your lease-make sure EVERYTHING is in your lease (who replaces air filters, who replaces smoke detectors batteries, who cuts grass)-be thorough with background inspections-make sure tenant is aware (and is in lease) on when fines occur for late rent and how much they areThose are things that first come to mind.In can be expensive and time consuming to set it all up the first time and do it in a way that protects yourself and your investment.Let me know if I can help in any way!

I read that if the tenants are a cause for health and property damage concern.. that means it’s an exception to evict...

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. 

We always have powerful battery operated lights to see the dark areas.

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).
