Real Estate vs Stocks - Which Is the Better Investment Option?
Investing can always be a complex idea considering multiple avenues for the same thing - buying land, property or other assets or stock investment. Especially when someone is planning for their retirement, it becomes really essential for them to choose wisely to make sure their future life is safe and secured. I believe investment in real estate gives you slow growth where as an active stock market trader can make money in no time if he/she is an expert. Whats your opinion on this? Looking forward some great discussions ahead.
