I've worked with several loan servicers, and no matter who you use, it's not fun setting it up, but I've had easier success communicating with OnePoint.They have a login portal to track payments etc, like you mentioned. 

I don't have personal experience with it, but when the app was first developed, I contacted the developer and put the app through a fairly robust test usage to see if it's something I would want to recommend to my clients (I'm a CPA).I think the app is great for its intended purpose and I do recommend it to my clients now (and have for about 18 months now). 

@Caleb Genry yet another request for your time tracking sheet if you don't mind. 

If you can find practice tests, that is my recommendation - that is what I did after taking the required time component and did not have any issues passing the test. 

@Ryan Vienneau I'm a Buildium customer too, and it blows my mind they don't have credit card tracking in 2017.

I wanted to start tracking my daily hours in the business and wanted to understand HOW I need to do this so it gets approved come tax time. 

You’re likely not hitting 500 hours (one of the tests) so you’re relying on the 100+ hour and more than anyone else’s time or substantially all the time in the activity.

You only need a place to track tenant information, payment history, maintenance, etc.

Use tools like:Airbnb Analytics: Monitor impressions, clicks, and overall CTR.IntelliHost: Analyze your listing for category placement and CTR improvements.RankBreeze: Track your listing's performance and ranking changes.You can also A/B test your photos by rotating lead images or running Meta Ads (Facebook/Instagram) or Google Ads to measure which photo drives the most engagement.The Airbnb algorithm is continuously evolving and every host should pay attention as new features are rolled out. 

The 500 hours test for material participation test has 0 to do with your W2 job.
