Quote from @Daniel Tanasa: Hello Terry, If you're looking to find houses that are in pre-foreclousure you can use a website like www.foreclosure.com and you can get the list of properties and start marketing to them. 

Quote from @Michael Ewers: Hey y'all, Wondering what is the best marketing strategy for obtaining off market leads?

The same money could buy 1-2 full properties that would rent for more, depending on the market you choose. 

I am convinced because listings sites pick markets they think make them more money to advertise.

Market fundamentals to consider: population growth, average income, median home price and average rent, crime rate.

Mom and pop sold the park for a price that the market would tolerate.

This is definitely the place to learn and network with folks in your market or the market you're interested. 

Use a buyer's agent that knows the market, contracts, negotiations, etc.If you really want to learn about investing, get a job in property management. 

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).

Do one task at a time in each app so you can compare apples to apples.Load a property with pictures and details.Market that property.See what your marketing looks like from the public's perspective.Submit a fake application to see how easy the process is.
