Does anyone have experience buying properties for cheap from land banks, renovating them, and renting them out/selling them?

You can have an email for each account and you should be able to set your phone up see multiple accounts at once should you get inquiries or messages.Just log into each account to make updates and price changes.

An even stronger indicator is that I am getting more and more orders to do BPOs (broker price opinions) for "banks".

We also have a bank account at a smaller Chicago community bank, but there technology isn't as good to be honest.I think @Jonathan Greene's main point is don't step over dollars to pick up pennies. 

If it is a larger bank/mortgage broker, you should be fine. 

Bigger Pockets is a great place to find a tax accountant that specializes in real estate taxation.

A bank will not give you the $ as you have to show ability to repay the loan. 

Sellers had multiple "accepted" offers and all were placed in interpleader accounts. 

So far it's the bank with the highest LTV I've found.

Sounds like internal accountability is really important to you!
