@Richard Benjamin Wilhite  Most multis in downtown are going to be a century old. 

It's like I need to find the deal of the century. 

Borrowing cash for interest is a centuries old practice but I’m wondering if anybody knows any creative ways to get access to cash with 0% interest?

You can pretty much look up recent national appreciation (last decade, this century, etc) and see universally numbers between 3% and 6%.  

I am buying newer properties, built since 2000, so I'm moving up more than a century. 

Finally, while on rare occasions real property does change hands a an extreme discount to market value, in the vast majority of the time a buyer, especially one without much experience thinks they’ve stump;ed across the “deal of the century”, they’ve mispriced the actual value because of something not readily apparent hasn’t been considered.  

neighborhoodScout ranks it 10/10 for this century

Go explore, make lots of offers and don't expect the deal of the century to fall into your lap.

I worked for a nearly century-old trucking company, YELLOW FREIGHT, which closed in August 2023.

Especially when Pittsburgh is home to homes that are typically built in the first half of the 19th century.
