Investing in real estate is the surest and safest form of investment as the value will appreciate, you are not affected by inflation (in fact, inflation is a benefit for you when it comes to rental income derived from real estate), you have total control over your investment and it can be used as a good collateral to secure loans.
No land is worthless. It may be of less value today but can make you a millionaire tomorrow. Do not underestimate any land. Ivana Trump said "I always felt very secure and very safe with real estate. Real Estate always appreciates" - that is truth. Stay wise, stay real!!
