Financial Analysis of the Deal: A Real Estate Investor's Most Important Skill?
Rather than just give you my analysis spreadsheets, my objective with this article is to show you how to develop your own. It is critical that you learn how to do so if you are to succeed at real estate and I want to encourage you to begin "playing" with Excel as soon as possible. This will be far more beneficial to you than giving a cursory glance to someone else's work because it is easy enough to understand. Consider this a case of teaching you how to fish and feeding you for a lifetime rather than giving you a fish and feeding you for a day.
You see, chances are my spreadsheets would not even be suitable for you because I am likely using a different investment methodology. Even if we are both using a similar technique there could be small differences based on our respective financing or some other aspect that means it doesn't quite fit.
But more important than any of that is this:
I have found that the greatest benefit of developing your own analysis spreadsheet is that you become intimately familiar with the numbers. By the time you've developed it and used it a few times you understand the numbers inside out and upside down and have a thorough understanding of what numbers are most important and what effect certain adjustments will have.
The PMT Function in Excel
Before we get into it you need to familiarize yourself with the PMT function and it's variants in Excel. PMT stands for "payment" and is a variable in a set of functions related to loans. The variables in this set of functions are:
- PMT – payment
- PV – present value
- Rate – interest rate
- Nper – number of periods
- FV – future value
- Type – payments due at start or end of periods
Here is a Microsoft page all about it – http://office.microsoft.com/en-us/excel/HP100698251033.aspx
One thing to be aware of is that the interest rate must be for the same time period as the payment. So if the payments are monthly you must remember to divide the annual interest rate by 12 when you put it in this equation.
Inputs and Outputs
In designing your spreadsheet you need to think about what inputs and outputs you will need to evaluate a deal. This needn't be very difficult. You can just begin listing variables down the left-hand column and you will soon figure out what other information you need as you go. Then you can drag and drop stuff to rearrange it later.
But as a primer here is a list of things that you could include as inputs:
- Property Address
- Value
- Price
- Closing Costs (can estimate as % price)
- Percent Finance
- Down Payment
- Amount Borrowed
- Term of Loan (years)
- Number of Repayments per year (needed for PMT function)
- Loan Interest Rate
- Management Fee
- Repair Costs
- Expected Rent
- Vacancy Rate
The output we are looking for is, of course, some form of return on investment. I'm generally looking at cash-on-cash return (CCR) which is the return on the cash that I put into the deal (not the price of the property).
CCR = net annual cash flow / cash invested
Ultimately though, you can use this spreadsheet to adjust various inputs so that you CAN meet your desired return. In other words, if your desired CCR is 30% you can adjust various inputs to determine what price you should offer on a property in order for it to be a viable investment.
You would probably also include some other key numbers in a tidy Evaluation Report such as:
- down payment
- closing costs
- total investment
- monthly income
- monthly expenses
- net cashflow
But once again the numbers you display will depend upon your investing methodology. These are more typical of a cashflow investor than a flipper.
What-if Analysis
And finally, you can use your completed spreadsheet to run various what-if analyses. For example, what if:
- you get a higher (or lower) LVR (loan-to-value) ratio loan?
- interest rates increase?
- your investor increases the down payment?
- you charge the tenant a greater option fee?
- you change the term of the loan?
- you reduce your management fees?
- you reduce your closing costs?
You can see what I'm getting at. Once you have a working model you are armed with some very powerful information.
The Layout
I've included this screen capture of one of my spreadsheets just to give you some layout ideas. Please do not try to model your spreadsheet exactly from this one. This is for a very specific investing methodology and many of the fields will not make sense for your siutation.
However, I just wanted to show how I divide the spreadsheet into:
- input area at the top (where yellow fields are inputs and blue fields are calculated)
- brief "Deal Evaluation" report at the bottom with some of the key outputs I mentioned earlier (for a cashflow investment)
- a "What-If" tool in the top-right corner

Possible Spreadsheet Layout
I hope I've given you enough information to just start playing with a spreadsheet and figure this out for your situation. If you have specific questions or difficulties just come back here and use the comment field below. Either I or one of your fellow readers should be able to help you out.
To Your Success,

Great article, I really agree with you. Research and analysis of the deal is the most important weapon in the bag of a successful real estate investor.
Thanks Scott for a terrific article. Too many investors don't go to the trouble to analyze the numbers.
Agreed that not enough investors analyze the numbers – it amazes me that people (even beginners) would invest in property on instinct, because they like the property, they think it will appreciate, or for any other reason – but it happens every day. That's what inspired me to write this one.
I think your comment about building your own spreedsheet is valid. Simply plugging numbers into a spreedsheet doesn't mean you understand those numbers or understand the answer.
There are some simple formulas in this business but unless you understand why the formula works, and more importantly, WHEN IT DOESN'T, you are really just guessing.

Hey Scott,
Thanks for sharing.The major problem with investors is the lack of drilling deep down to make more meaningful insights with data. I like the layout of the spreadsheet, can I have a sample? One can use this to build expenditures on savings on spend too
I'm having a hard time with excel at the moment. Your post has helped shed some light on a couple of issues. Thanks very much.
Nice post. I think you covered almost all of it. Most people never look at all the numbers or do not want to. You have to make sure your getting into something that can and should make you money before you buy any real estate.
Thank you for providing such an in-depth look at investing. Rarely do people analyze figures like you did which helps tremendously.
Your post just furthers my own conviction that we can't just act on "feelings" alone. Drilling down into the nitty gritty of finance is so much a must.
Excel and financial computations are such important tools when evaluating investments. This information is invaluable.
Wow, an excellent and a VERY concise breakdown of how to number crunch a property investment deal. I think you will find, most people overlook this important step and like to stick to the "back of the envelope" numbers approach, which often proves risky. I'm bookmarking this
