Can you help me find a good property management MS Excel sheet
(perferrably) or property management software?

I am managing less than 25 units, and I know there are a number of
property management software programs out there, but after using a
few, my belief is that a well-designed excel sheet would make more sense and
provide similar (better?) functionality.

For example, you might think that a program like Quicken's Property
Manager would suffice. But it's lacking such basics as including a
running total alongside each transaction (There is only a single
running total). And if you make a mistake, it is virtually impossible
to backtrack and find. How about a field for your check number, the
singular way many managers identify checks/transactions? It doesn't
have one. One of the 8 or so automatic fields they do give you is unit
number. Problem is, it's a simple numeric assignment based on the
number of units you input when you create each building's account, and
it can't be altered. Apartments lettered instead of numbered, numbered
in partial sequence, alpha-numeric, by floors, etc? Tough luck. These
are just a few of the problems or basic design flaws in this program.
My past experience with some other programs also is that they make the
simple complex.

The program I desire doesn't have to be perfect, but using the above
for example, for my relativly common and straightforward application,
I think an excel sheet that has been in use in the real world would
give me the
same, or maybe better, functionality. And the "open" nature of an
excel sheet is more easily portable over time and different operating
systems. That said, I'm not excluding a property management software
program, designed for the smaller manager(i.e., not unnecessarily
complex). I know that google Answers are fielded primarily by
experienced researchers, not necessarily by, in this case property
managers with experience in my application. However some practical
(first or secondhand) experience in actually using the tools desired
would be appreciated, since, by definition, most software products
portray themselves as the greatest thing ever.

Thanks.
