I posted a while back on ways to get large checks quickly into interest paying accounts. Many good paying accounts are "internet only", and lag time for US MAIL becomes costly, and WIRES are still fairly expensive at some firms.
PLUS .... almost everyone puts a hold on transferred funds (except by WIRE). Some pay interest on those funds while in "hold status", and others do not.
I was looking into various options when I discovered CIT BANK. May not be the best option but seems to work for me. BETTER than ALLY BANK as a HUB. Seems to have unlimited numbers of external ACH links, and at least for now, have 250K/500K daily limits for ACH. I have also found, at this time, that most of the ACH complete with 1-2 days, AND they pay interest while in a HOLD.
Have not done any yet, but have ZERO fee for incoming wires, and either Zero or $10 for outgoing depending on your account balances.
HORRIBLE customer service via wait times, but I think I have figured out one thing .... call after 10am PST. Still can have some long waits, but seems to be less than if you call prior to "opening time" for regular staff.
NO paper check writing, but between ACH and WIRES, they are a great alternative to ALLY BANK. Plus, for now, they are doing a BONUS offer for new accounts with PLATINUM SAVINGS.
