I source off-market parcels for some of the development work I do and have had the most success by just calling the owners.

Once you receive an application, run credit checks, background checks, research the information provided on the application, and take the time to contact each and every one of their references and previous landlords; it’s the best way to learn all you can about how they treat a property, directly from the source

I work with the 1-9 unit range so having 10 would fall outside my options and it would be harder for me to source/qualify my clients.

I work in pharmaceutical sales which affords me a decent pay and flexible schedule and I truly enjoy it so my properties will be passive income which will further support my family.My parents have a college rental at the University of Dayton which does very nice and I like the idea of that model as a fairly safe and reliable source of passive income.

My question is, what are some great sources to find more in depth information about certain locations/neighborhoods? 

As to what to charge, there are several online sources that can help you understand your market, or to Eli's point, find a local RE and get their opinion on the market.

I think it will make the MLS as a source of deals much more competitive. 

Is this indicative of a less comprehensive data source? 

@Philip Diers  If you're looking for downpayment loans, typically those are 2nd position so friends and family will be your best source. 

I am in my preliminary search phase but these questions kept popping up in my head and I didn’t know a better source of knowledge than the bigger pockets community.Any help on this topic is appreciated!
