Purchasing property is usually the biggest single outlay of finance that anybody makes, but most of us are willing to do this since one is almost guaranteed to make a return on the initial investment. Whilst house prices fluctuate and there can be dark times when prices slump, over the longer term property prices almost always increase and investment is assured. Not only does the investment provide a roof over our heads, but in many cases where a second property has been purchased, it provides an income stream from rental opportunities.
