I've been using Dealcheck.io to do deal analysis but have been hearing a lot about Backflip recently.

I would encourage you to pick a country and then do the research on the way to buy real estate in that specific country. 

Quote from @Drew Sygit: It's like first responders: people don't really care about what they do until they need them. 

If you're doing a rate and term refinance, there's typically not a seasoning period but again it's common for lenders to require it be rented first.If you're doing a DSCR cash out refi, it may not need to be rented first but you're probably paying a higher rate.Your best option is to call a loan broker you trust and go through the options based on your current situation.

Why do you care but also why would you send them to a church.

I suspect even the banks who are aggressively expanding are doing so merely to sure up their geographical presence  to in order to expand their customer base but will then pull back on their branch numbers.Unless there is significant term remaining on the lease, there are other retail concepts that would be deemed more marketable.

If you are specifically asking about the requirements to get licensed you'll want to do a google search for you local laws and requirements.
