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

Check online reviews and test their responsiveness.

However, their presence in the markets raises the entry point for everyone and the actual investors need to start breaking their "rules" in order to be competitive. 

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.

Nearby suburbs like Lakewood, Rocky River, and Fairview Park also offer solid investment potential with generally good stability and demand.For employers, Cleveland Clinic is a strong presence but hasn’t significantly gentrified the surrounding area.

@Joshua Tobin They all pay online through AppFolio.

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

The successful wholesalers I know spend $8,000 + per month on online marketing, SEO, SEM, landing pages, lead conversion, etc.  

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