Do not believe the lie that you can adequately manage your vacation rental with your iPhone and some far east "customer service agents" to take the occasional phone call.

With dropbox, I can work on my iPhone or hp laptop or desktop and save all under one roof.

I found a calculator but it won't work on my iphone.

A lot of investors who bought in 20-22, who got bad advice that they could manage a place with their iPhone, are dumping their properties as a result.   

In other words, if the person has an online presence, you can find out many things about them and then add them to your contact list.5) There is a nice follow-up feature that you can setup.6) Integrates with alot of the other different services that will allow you to "do business within your business".7) Can be used from within any browser and also has an IOS app for both my iPhone & Ipad.There is more that I can say about the service, but, I'll stop here. 

In addition to this, your photos by your listing agent look like they were taken on an iPhone.

It depends on the State and the County, just google "real estate photos with iPhone" and you can find a bunch of services. 

There's a lot of great advice here, but the first thing I noticed was the dark photos that look like they were taken with an iPhone.

Not to mention I ditched my iPhone 5S for the Samsung Galaxy Note 4 (battery life = sooooo much better, lasted TWO DAYS without charging) and I don't have iTunes on it (and I probably won't install it either). 

Or the 14 streaming subscriptions, and man alive there is a new i-phone that has 7 cameras and it's "only" $4,000 I mean how could one possibly go without the 7th camera come on, and the current phone is like soooooooo old you've had it like 6 whole months....... wtf.....
