I'd say for most, it would be accounting, timing on collections or accounts receivables that tie to notices of rents due.
What the techies refuse to understand is that real estate is not a series of 1's and 0's, you can not quantify judgment, intuition, intrinsic aspects of value or possible potential as you might with some widget like a car meeting popular demands. Real estate is immovable, unique and assessments require knowledge and experience, you can't put that in software.
Only repetitious functions can be made easier with a computer, while that may include statistical forecasting, it can not make an informed buy or sell or lease decision for a particular parcel or improvement.
While the geeks may be able to design something that can fix my breakfast, they can not solve my outlook or assessments of real estate.
I have gotten requests from others trying to find a silver bullet with software development, the issue is that they do not understand real estate. When you have unknown unknowns, you can not assess or quantify variables that may or may not be applicable, not until we have intelligent software that can think like we do. It might be one the way, but it ain't here yet.
Everything else will simply be files, storage, manipulations and formulas which aren't really rocket science.
So, as to your question, what aspect of administration of real estate which is similar to other businesses are you interested in? We already have accounting programs, inventory control, sales forecasting, population trends and construction management, what area is there that can be reduced to be defined by 1's and 0's? :)
