Vrbo has free price automation software.I use Excel for book keeping.I don't pay for any third party software, not really needed on 1 or 2 properties.I charge a little extra for cleaning fee than actual cleaning costs.

But I have many automations set up and have very detailed financial statements I generate every month so it definitely took me a few months to get the hang of it.

It's automated, secure, and reliable.

It is a fairly automated process for them

All you get is what you can export/import via CSV file:(We use Propertyware, have experience with Buildium, and have played with Appfolio and RentManager.Buildium is for smaller companies.The other three are tied, the differences being how much automation & customization you want to do.If you don't see yourself growing beyond 150 units, go with Buildium.If you're not very techy and plan to grow over 150 units, we'd recommend Appfolio.If you're techy and plan to grow over 150 units, we'd recommend Propertyware or RentManager.Of course, schedule some demos, take GREAT notes and them make your decision.FYI - there are MANY new options on the market, RentRedi, TenantCloud, Apartments.com, Hemlane, Rentec.

I have great properties that sell themselves.I love the analytical tools and free price automation Vrbo provides. 

Which interestingly enough now they can actually define themselves as literal human-cat's and even demand a litter box and it will be done.

We built into our automated messages to ask for feedback and do so prior to a review.

They won't be as automated though.
