The second component of a good real estate investment spreadsheet is a long cash flow projection period. Property investments are typically very long term ‐‐ from 10 to 20 years on average. In particular, if you are buying real property for long term portfolio holdings, it makes sense to have at least 10 years of monthly or quarterly data, and even up to 30 years. This ensures you capture the entire future cash flows, and enables a much more accurate determination of net present value, internal rate of return, and capitalization factors.

The first consideration is how clear and accurate the Excel formulas are. The keys here are easy accessibility and logical flow of the formulas. That means they should be either directly coded in the spreadsheet cells or written in an accessible VBA module, open to the user to view and change. Both of these approaches provide the ability to audit and test the formulas without requiring complex actions on the end user‘s part.

Examples of third party evidence would be sales invoices, purchases invoices and bank statements. Financial transactions where no receipt exists can still be entered in the business books although all transactions not carrying third party evidence could subsequently be disallowed for tax purposes and certainly would be if the amounts entered indicated unusual income or expenditure.

Producing an income and expenditure statement using single entry bookkeeping is little more than making two lists of financial transactions. Those lists being one of sales income received from sales invoices or receipts issued to customers and the other of purchase expenditure being from purchase invoices received from suppliers. To record sales income it would not normally be sufficient to simply add up the total of the invoices as such a summation does not leave an audit trail of the items which have been included. A written list of sales invoices does provide an audit trail.

Managing the household finances is made a lot easier when you use a spreadsheet. When using a spreadsheet program for budgeting, you need to use formulas in calculating all the totals. That way, you make the process much faster because you will not have to get the totals manually using a calculator. This also prevents inaccurate computations on your budget.

Second, remember that whatever can be measured can be managed. Develop a system wherein just a few look at some numbers can tell you the health of your operations. But this also depends on the soundness of the system. If someone can just fill in numbers they can induce you to think in ways that may not be desirable given the fact that you have to manage the operations.
