What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

But right now, I wonder if a total newbie in this should really be trying to get a small loan (50k) to purchase two house around 60k each?

They also have a 90-day litigation period where the former owner can contest the tax deed sale and take you to court.If I bought a property (or land) and want to re-sell it within a few weeks, what forms/documents do I need to give to the new buyer?

I purchased a duplex at a shore town in NJ.

Apartment buildings can be a great investment but you have to buy in an area that is appreciating and purchase a building that has good returns, hi-occupancy, and little overhead. 

Purchase Discount: It's crucial to buy properties at a deep discount if you plan to BRRRR and get cash back.

The question is, how much leverage is the investor using to purchase the property and at what interest rate.

My first real estate investment was in Syracuse NY in 2005.I relocated to Augusta, Georgia in 2006 to learn with a multi-family investor/mentor.And then in 2009, I founded Auben Realty, which has grown from a small local shop to a regional presence with current locations in Chattanooga, TN, Columbia, SC, Greenville, Atlanta, Charlotte and Jacksonville.Recently, Auben purchased a property management company in Kansas City to begin our Midwest expansion.

The owner of the property is a relative, who purchased the property (condo in Miami) for $200K in 2014. 

My plan is to hold onto it as a rental property, targeting Section 8 tenants, as the rental income is quite attractive at nearly $1,500 per month.Here's the challenge: The property's purchase price and labor is below $40,000, and I'm uncertain about my ability to secure a traditional mortgage for a property at this price point.
