Hopefully this was not stated some where else in the forums but I could not find it.I am browsing listings for small multi-family units in the metro Detroit Michigan area and reviewing the stated current rent and NOI.  

I'd also suggest to setup a Chrome extension, the one I used is called "Email Extract", as you're browsing through Facebook Wholesale groups, many of them like to add their email address.

One way to begin gathering data is to browse the big listing sites for properties similar in geography, amenities and size to what you envision buying - see what their rates are and check out their occupancy by looking at their calendars.

Browse investment opportunities, ranging from home fix-and-flips to new construction and commercial properties.Read all the supporting deal information, including the pro forma financial forecast, comps of similar properties, developer team expertise, property photos and due diligence documents.Invest from your bank account to our escrow account, right from your phone (or, if you prefer, switch to a computer and web browser).Monitor the progress on your projects, through weekly written reports, photos and videos.There’s no cost or obligation to explore the app, which is called “iFunding – Real Estate Investment through Crowdfunding.”

I was browsing through the forums and came across a thread started by a landlord in Portland, Oregon.

Lease Options (or Option to Purchase Contracts Executed With Lease Agreements if you browse NCGS) in NC are also regulated.

Holy cow - guess I shouldn't be browsing the boards while post op.

You might be able to browse them online or at least partially online. 

I have read 20 or so books on various strategies, including browsing any quality information I can find online.

Just browsing the listings, there is a huge variations in prices.
