Opportunity to buy an old bank

[Justin Boyd]

Question: 

When buying an old building (constructed in 1900 with an effective build year of 1960), what should I look out for and ask about? The paint is chipped so I'm assuming there's lead paint and there will likely be asbestos and lead pipes for plumbing. What kind of funding can I acquire to develop this property?

Story:

While looking into buying some land I stumbled upon a commercial building that was the first bank in the city. I've never invested in commercial real estate but the price they want to sell for seems very attractive. The owners are retired and looking to sell the property. The building is small (1200 sq ft) but it has a charm with the vaults that I think could be rehabbed into a thriving business. The bottom floor is approved for commercial business and has the main vault, some marble flooring, and a back room office and restroom. The upstairs is approved for short-term and long-term rentals and has a kitchen, bathroom, and a Victorian room that could be a bedroom.

Notes:
-There are three vaults, one on each floor. None of them are functioning.

-The building is not certified as historic and can be rehabbed freely.
