That is a tough break, pattyb53 . . . a very tough break.
You would be limited to $25,000. But if the money is available at EBSB tomorrow (Wednesday), and once you have confirmed that availability, you could early in the morning your time do an ACH pull from EBSB into your Alliant account. The money would be available in Alliant next day Thursday. Thursday morning early you slingshot the funds to your Andrews account and it is there Friday in time to get the deal you want, which closes this coming Saturday, March second.
Alternatively, and I think a better option, would just be to wire the funds tomorrow, once they become available, direct from EBSB to Andrews. That way there is no limit on the amount you could transfer. Only problem for you with an eastern to eastern wire is need for you to initiate your wire very early in your day, but of course not so early here in the east.
The above options assume you already have made the proper ACH connections or have already spoken with EBSB about wiring funds and understand their procedures, precautions, security measures, and so forth. Financial institutions, some of them, can be rather persnickety about wiring funds when you are unable to appear in person to order the wire. But the ACH, within the Alliant $25,000 limit, should work for you straightaway provided all of your accounts are already connected . . . . which they should be.
Back now to liquid accounts:
I’m having a bit of fun myself today with the accounts I opened this morning at PurePoint. I assumed the money, currently in Alliant savings, will not be withdrawn from Alliant checking until early tomorrow (Wednesday) morning. Then I got cold feet.
So I set up Alliant’s free overdraft protection just in case.
The game plan all along, if this goes as planned (nothing is ever for certain), is to transfer the funds manually before 6:00 am tomorrow morning from savings to checking, thus limiting the Regulation D hit to just a single withdrawal. But if it turns out I need my backup, and plan B kicks in instead, there will be three Regulation D charges, possibly taking me up to six for the month. With a bit of luck that will not happen.
So anyway, I’m hoping for the best. Alliant runs its ACH files on central time, and I’m on eastern time, so I’ve got 'em by an hour.
