The kind of mortgage you choose when investing in real estate can determine your overall success. If you choose the wrong kind of mortgage you can end up losing your property. If you are buying a property and your intention is to rent it out the worst kind of mortgage you can get for that property is an ARM. An ARM means an adjustable rate mortgage. With these mortgages the interest rates can go up or down after a set period of time. http://realestatefacttips.blogspot.com/2009/09/what-kind-of-mortgage-to-choose.html
