This would not have been possible without the BiggerPockets Website, Podcast, the books I have read and a lot of persistence, patience, and planning. 

In some areas you can go on the county website.

For a list of all fair housing groups, go to the Housing Rights Center’s website at www.hud.gov.  

You are off better off looking at a local realtor's site or searching off-market. 

Hello Everyone I haven't posted too much on this site until now but Ive been a member for years.

@Sean Monahan You can still inspect your properties as normal - you'll just give your standard notice and communicate that to Airbnb guests.Loftium requires long-term tenants to hold renters insurance, and Airbnb provides $1M of damage protection and a separate $1M primary liability insurance for every booking.Most repairs don't get in the way of Airbnb hosting - i.e. if the stove is out, that can be communicated to guests - and as long as repairs are made on a timely basis, there's no penalty.We sign a standard 1-year lease for the first year, and can sign a longer lease after that if both sides are happy with the process.Feel free to check out my profile and the Loftium company profile on BiggerPockets for our website with more info. 

Lots of great info on this site to help you along.ThanksRobert

You will never factor out all risk and the web will only prepare you so much.
