how do you handle the bills finding where you are -- like the timeshare fee bills and tax bills for those??? I know for us, some companies are not set up to have the bills go to our bank's checking account.
At the beginning of the BLOG, the 2008 postings, i tried to cover the many logistical problems we had in setting up this lifestyle.
As for bills, ALL bills, the regular ones, like you, are all set up auto pay either from the credit card or from the bank. We do almost everything on line and watch the bank accounts on line very very often. I take care of my mother's accounts and so continually monitor that there are enough funds to pay for her home care! [Like yesterday, the bank's check did NOT get to the care-giver.....had a long session on the phone with the bank, to no avail, so had to drive to a neighboring town today to send an Express Envelope.]
Those bills which come irregularly, like the annual M/F and taxes? we have four ways to get the amounts :
1. We have a UPS box in a UPS Store in Ohio and they can forward all mail sent there to us, wherever we are, upon request. I can either call or email them. They are super nice to work with! Some companies have that address as the mailing address. There is a fee for forwarding stuff - that is, it is bundled and you pay the postage to forward so we select which comapnies have that address: that mail that we will want to have wherever we are.
2. Our son's address in Seattle is used for all magazines, packages (mail order) and certain other bills, like the Seattle bank, cell phone, and actually Wyndham and RCI and a few others use that address. That mail is not forwarded to us - that family just doesn't do much snail mailing in their lifestyle

so we don;t want to bother them with that. Because of the UPS fee, we have magazines and other heavier non-urgent items sent there. We are there very regularly to see my mother, hopefully a trip every 4-6 weeks, (sometimes it is longer), so we pick up the mail then.
3. Internet. We are very aware when the M/F's are due for the properties so we watch for the bills and in one case in particular, UVC, we get on the internet to pay every year.
4. By telephone, especially if we want to deposit a week into an exchange company, we call and pay with a credit card. I just deposited a Sept 2012 week.
I am sure you all do the same things. It's just that we have to keep extra careful account - and with spreadsheets, of course. The hardest one for us to keep track of is the 6 weeks at Townhouses at St Aug Beach and Tennis Club, since 3 are floating and 3 are fixed and they have different contract numbers which we have to figure out,and if we have paid in advance because of a deposit, etc. We've almost figured out how to keep them straight!
You do bring up a potential urgent problem that could occur,though,and that is if the IRS decides to audit us, sends it to Seattle and then we aren't there for a month! and maybe miss the appt deadline. Oops!
So far, that has not happened, but in planning for every possible eventuality?
