Hey guys I'm 16 years old looking for some ideas to make an app for both Android and iOS, what are some ideas for app that would be very useful in today's society?

Do you guys use any of these for iOS or Droid?

., I would seriously consider trying to leverage as much as possible - do an IO of some sort - and reap on the positive cash flow.

I will make sure my iOS developer sees this.

Octavian, at one point I'd installed a bunch of real estate apps, but like most of my apps, I found that I rarely used them and eventually forgot about them.About 6 months ago I upgraded my phone and don't think I remembered to install any of them on the new phone, and completely forgot about them until you mentioned them.For agents, the RI statewide MLS recently switched from Fusion to Matrix, and I think part of the reason for switching was a better app/mobile experience, so that's probably one of the few apps I could recommend.Other than that, maybe Google Sheets or Numbers for iOS - spreadsheet apps - would be useful.One other app I could maybe recommend would be Venmo for payments, as some tenants and contractors have asked about using that.

I think when I break it down what I'm trying ti ask is, if I get IO for 3 years, can I then use that interest only to calculate what I can pay for the property along with what a pro forma NOI would look like with the rent increases?

That IO loan has to have specific terms attached to it, and the entrance/exit strategies used on the series of individual properties MUST be treated as a string of properties...and not as indipendant properties.  

I have an iOS device and couldn't find the app. 

And the loan may be 40 years but the IO period likely isn't.

Thank Brendyn Dabrowski , I'm using the iOS application right now due to the fact it's my laptop nothing more because I used it fine on my iPad and iPhone and was able to long in and out so I guess I need to get it looked at
