Certainly under $100 even if you have to advertise it in a newspaper to finish the process.  

In 1987 I bought an old Cape built in 1942, the Pearl Harbor attack was on a front page newspaper stuffed in the bathroom wall to hold the soup dish in place during the build.The stucco had seen better days & was peeling away from the wire mess & leaking badly within the wall cavity.

I pick up the newspaper and I check out the shopping malls, restaurants and main places of employment.

I look at craigslist, the newspaper, Facebook marketplace, see what rentals are going for in your area.

Read the local news paper! 

That and newspaper ads was where people learned about properties for sale.These days, people are flipping through Zillow while sitting at the toilet. 

Couple hundred bucks and you are off to the races, can advertise houses, put signs up, newspaper ads, flyers etc. 

Monitor deal sources - auction.com, homepath, HUD, local newspaper foreclosures.

My local newspaper is near worthless for news but a great source for foreclosure listings and auctions. 

Divorce and probate can be found in a local newspaper.....
