How do people maintain their property info?

Hi all,

I was wondering how people maintain their property portfolios when they have grown their portfolio to quite a large number of properties.

It becomes difficult to keep across the total rental income you’ve generating, your loan repayments, and equity and all your documents.

I am referring to folks who own a significant number of properties and may often buy a number of properties at a time (similar to what was described in steve’s book) – do they maintain their portfolio info themselves or give it to someone to maintain it on their behalf? Any companies who do this for property investors with large portfolios would be good to know if someone can let me know that will be useful.

If you could also provide some ideas on how you maintain your portfolio info yourselves too that would be good, e.g. in excel doing it yourself, some other way, or using some external provider will be very useful.

Thank you.
