Love me a bank account bonus!!! Jealous you've got Suntrust available
see
@Albort and
@SBWB48 already got your ach / acronym and the importance of pushing the money info going!
Warning! I'm going full on bank bonus nerd now:
The best DD is a real DD. If you can do a real DD (paycheck, government payment) that's what you want to use. Just transfer the money out of the account after it hits Suntrust to your hub/main bank account! No need to make Suntrust your permanent bank for any time period. If you do not have the ability to DD then you try to trigger via bank account transfers. I agree you don't want to rely on just one to trigger it (I almost lost a $300 bonus with PNC by doing that!). Best to try a couple banks that have been known to work in case anything has changed from the last DP.
Keep a spreadsheet! List your bonus amount, bonus requirements, earliest allowed closing date without being charged, fees on the account & how to waive the fees. You'll be grateful not only for the info to keep the accounts fee free and nab your bonus but also for tax time next year. Bank account bonus are taxable income and you will/should receive a 1099-INT for the bonus amount. Most banks send these out, but sometimes a bank chooses not to issue a 1099 (I'm looking at you Wells Fargo and you're issuing some people 1099s but not others ridiculousity!), your 1099 gets lost, or they issue an erroneous 1099. Also, the bank may say "we don't 1099s for that" today and then decide it was an error and come back a few months after tax time with your 1099 (HSBC 2016). If you know you owe taxes you can report the proper amounts on your taxes regardless of the status of your 1099-INT with the bank.
Hub account!! Personally I suggest and use Ally. (DoC has one report of it being a HP to open at Ally but I saw a few DPs on reddit that it does not. Don't sign up for overdraft protection! That's usually what triggers a HP when opening a bank account.) If you really want to delve into bank bonuses you need an excellent "hub account". This is one that plays well with other banks basically and Ally does that. You can link up to 20 accounts (it's commonly thought there is no limit but I got really into this last year and discovered Ally did have a limit) and I've never had a problem with any of them and Ally transfers. Ally has mobile deposit, reimbursement of atm fees, no minimum balance req's or monthly fees. They even pay an anemic 0.10% on their interest checking account right now (beats the pants of Chase Savings 0.01% though!). I'd open an Ally and try the DD from there if you have to go that route. Also, all those other banks (ING is no more, never heard of Adventure) run bank bonuses for signing up for new accounts so you'd want to wait to open accounts at those banks but as far as I know Ally doesn't do that. (Especially do not open a Capital One account if you've never had one, very lucrative bonuses when they run them but if you've EVER had that type of account at Cap1 or someone they bought (ING) you won't qualify for their bonus. Don't want to shoot yourself in your bank bonus chasing foot here setting up a hub account.)
