You can use tools like spreadsheets or time-tracking apps for convenience.

Also, ask your agent to do prior rental verifications and to run the applicants through Forewarn app.

Get on the meetup app or facebook groups and look for realtor events and try to become a vendor at one.

There is an app you can download called EZ Calculators that may help you somewhat.  

@Tamika Davis To your point, it is difficult to find one app that does it all.

The app is horrible. 

Jill,Check the app/website turnoverbnb.

Then the prices lower towards the date and you end up booking at a low price or worse just being vacant.I think manually pricing your STR'S is a much better approach.So many people are looking for the next cool software app to buy a subscription to.

I'm also intrigued by the Shovler.com app, but I fear being left hanging in the event of a big snowfall.

Quote from @Jimmy Rojas: Thanks for the reply, i think it may not be worth it after all, may I ask did you use a calculation app to come up with the mostly payments, if so, care to share it with me.One more thing.
