As the year begins to draw to a close, many investors are sitting back and looking at what was almost an unprecedented period in terms of owning property. It is often also a good time of year to take a look at the performance of your portfolio and see if there is any room for improvement – this is something that even the healthiest portfolios needs to go through every now and then (particularly in an uncertain economic climate).
5 Stages of Stress Testing Your Portfolio:
1) Data Collection: mortgage payments; rental receipts; voids; maintenance; repairs; tradesmen labour costs; insurance; bank charges; gas inspection costs; transport; fuel; EPC charges (you may want to also add your property buying costs, if any); interest payments on other loans related to your property business; legal; bookeeping and other auxiliary charges. You should ensure that the information you use is accurate and up-to-date to ensure that you are getting a clear picture;
2) Net Operating Income: this is essentially deducting the total amount of money you spend on your portfolio from the rent you receive.
3) Future Cash Flow Testing: whilst the bank base rate in 2009 has remained historically low, predictions vary as to what will happen in 2010 (for example, many see that the effects of quantitative easing could boost inflation levels). Either way, examine the cash flow (net operating income, as above) from your properties through various rate increase increments remembering that long term average interest rates are between 5-6% (look at historic interest rate figures whilst doing this analysis). It is through this analysis that you can often weed out any issues with your properties that may be getting overlooked (and potentially save some money) – for example, are you spending too much on maintenance, repairs, insurance etc? Could you keep some of the cash-flow by managing the properties yourself? Could you potentially turn any of your properties into a HMO (and benefit from an improved yield)? Would acquiring more property make sense (to balance out the negative cash flow you may be achieving)?
4) Releasing Money from Your Portfolio: for those who had bought property before (and during) the onset of the credit crunch, you should take a look at our monthly factsheets via the Investor Hub as well as keep your ear to the ground on your local market to track approximately how much the value of your portfolio has dropped. Look at a number of different growth scenarios to determine when and how the equity level in your property will increase in order to determine when you will able to release cash (either by selling or re-mortgaging). Note that some areas (such as London) have been less affected than others and are predicted to go up in value quicker. Start with a pessimistic view of further negative growth right through to being optimistic and see how you will be able to handle every situation (good and bad). You should also bear in mind the fact that lenders are being particularly stringent with valuations – it is therefore better to take a conservative approach (if you are interested in subscribing to access unlimited Hometrack valuation reports click here);
5) Major Costs: Lastly, and often forgotten about, is to test worse case ‘real life’ situations against the performance of your portfolios (refurbishments / large scale repairs, boiler replacements, bad tenants etc.). These costs do build up, particularly after you have owned your portfolio for some time.
With points 3-5 above, the best form of stress testing is to ensure that you will be able to sustain the portfolio if both interest rates increased; the value of your properties continued to decrease and you take into account a number of refurbishments etc. (whilst always looking at your net operating income).
