This management software is great for some who are not tech-savvy, looking for a user-friendly interface, and if you're doing either rent by room or rent by unit model.

The Roku interface is very simple.

We have a realtor in our family just so we can interface and work with other realtors. 

Also gives you more access/control of the reservations and communication with the guests (the control they offer through the API (application programming interface) actually makes it one of our top picks as a platform).Having said that, yes, if you're not using a PMS then VRBO is going to use whatever payment system THEY prefer, and you may want to stick with Airbnb.

It is very cheap to use, a simple interface, and very efficient to just take photos of the receipts from Home Depot or Lowe’s, etc. 

Plus with these databases in the future there could always be ways to interface them to networks/web stuff since its all standard stuff

I know that FCIs web interface is a bit clunky, but it works.

I envision one platform that interfaces with third party apps so that you just need one login to access other software products.

StreetEasy's search interface for NYC is insanely good, they have a customized map boundary search feature. 

That can be a bit hard in listsource as it doesn't have an interface for looking at the details behind each property, but you can often still get there between it and the counties website.
