Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

Now they have a feature on their website to have a rent determination before you get the tenant.

I would suggest looking up similar rentals in the area to see what the trends are and what features are offered at the price point you are expecting.

Hey Lia,First and foremost, congratulations on taking the initiative to embark on your real estate investing journey at such a young age.

First and foremost is the cost of it.

I was turned down by all of the companies that are often mentioned here (Proper, Steadily, Foremost, American Modern) and many others. 

I do know that the pricing varies based on the unit count as well as what level you sign up for; but overall, it's super user-friendly for tenants, PM's & owners.Plus they're always updating their software and adding new automation features to make everything so simple as well as well as great customer support. 

This is one of my favorite features of Bigger Pockets especially for asking specific questions.

I personally use Buildium but I'm always looking out for new features and pricing models from the others.

The district constantly evolves, with new features like Netflix’s “Army of the Dead” virtual reality experience.
