What's a good way to fax property documents?

I'm dealing with rental agreements and property-related forms, and some offices still prefer fax communication. Most of my documents are stored on my phone. Does anyone recommend an online fax service for handling this kind of paperwork?

Property paperwork tends to arrive at inconvenient times, so having mobile access makes a difference. I found https://comfax.com/ while researching ways to send documents without a dedicated machine. Municorn Fax App supports faxing from smartphones and browsers. I like that approach because it matches how I already organize rental forms, contracts, and other important files.
