I don't think you'll be missing something with either choice. 99% of what I end up doing is with pretty basic stuff: e-mail, browser, maps, flashlight app (amazingly handy), camera, weather apps, calendar, productivity (pages, numbers, and keynote, the iOS equivalents to word, excel and powerpoint), calculator, kindle app, iBooks (mostly to capture .pdf documents), banking apps (from your bank), open table (restaurant reservations), trip advisor app (handy for finding stuff near you, though the map apps are pretty good at this, too), airline apps (flight status, online checkin), clock (haven't used a watch in years, also for timers, stopwatch, and alarm functions), pandora, fandango, flash seats (concert tickets), and a few others.These phones are really handy when traveling.

I'd love to hear from folks and learn how to fill in some of the blanks and also learn where I could optimize a bit more.Syncing Calendars - I use Guesty for Hosts.

Find comparable listings and use their calendar, nightly rates, property description, reviews and future occupancy levels to make a good assessment THEN refer to AirDNA.

^^ @Katie Miller - not sure what you mean "can I link to my site"   Oh... do you mean can I link my calendars?  

So s SFR to a 4 plex or commercial or raw land or any other type of real estate is fine.The key in those scenarios is to pay close attention to the calendars as you sell properties to go forward into the larger one.  

Manage Reservations: Keep your calendar updated.

It even syncs with my calendar so that I can have different setting when the houses are unoccupied.

Supposedly you can sync the thermostats to your booking calendar so that it will only cool when you have a guest there and put limits on the temperature like you are describing. 

. - maintenance requests (When your tenant or you put the maintenance in you can review it modify it ask questions then send it to your handyman via email with all the information so they can give you a quote on repairs) (it also tracks if they are still open or closed, you can make it where you or both you and the tenant can see the maintenance request which is good because some of the minor repairs I keep track of until tenant turnover so I can fix later)- rent payments, (they even allow for a security deposit return electronically vice mailing it)I use Stessa for all of my accounting.One thing I would like for Innago to add is a calendar option inside of the software.
