I am very weary of online places because it is very hard to vet out a company.

Now they write the offer and send it online.

We have lots of automated processes - All online rent collections, inquiries, signature requests, and late fees.

So if you look them up online you will see the owner is a Wyoming LLC, then you go try to look up the owner of the Wyoming LLC and you won't find it.

So a ways off from posting my mid-term rental online. 

Its a legitimate claim against you. 

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.

I'm looking to list my property with them but read some horror reviews online from guests (but not hosts). 

Hey @Tarcizio Goncalves, QuickBooks Online allows for everything you need. 

For building a buyers list, I’d recommend joining local real estate investment groups, both in person and online.
