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.

And they all have the same lines how they are the best agent out there . 

Residential investing is not rocket science, knowledge is not the issue: there are many good books out there that walk you through every detail you need to know.

There are really great REI opportunities in different markets - markets in the Midwest and Southeast of the country are particularly lucrative - where not only are the purchase prices reasonable for most RE investors, but the homes are turnkey (new builds or completely rehabbed homes, tenant ready, systems 10 years of life remaining on them, property management teams in place) with appreciating home value AND appreciating rent.

@Jim LynchSome typical minimum tenant screening requirements look like the following, but it depends on your market:-Renter has a gross monthly income of 3x more than the monthly rent-Minimum credit score of 650-Renter must have no prior evictions-No felons (or other notable criminal history)There are a number of different tenant screening softwares out there such as Zillow Rental Manager, TransUnion SmartMove, etc.Be sure to complete an employment verification by contacting the renter's employer and confirm the details they shared with you, landlord verification (if they have a previous landlord), credit check, and background check.

The TL;DR here is that there are 10,000+ unique banks and mortgage lenders in the US.

You'll end up finding out if there is no motivation to sell at a certain price, then it is not worth consistently asking for the same price that the person said no to.
