A challenging part of the business
The mother of all challenges in real estate investing is the rental market. In order to be a successful landlord you will need exceptional diplomatic and communication skills. Your tenant will test you to limits that you never thought possible and you will be given the runaround by the estate agents as they seek to minimize their loses at your expense. You will be insulted and called every name under the sun just because you happen to exercise your rights to collect rent.

The government will take every opportunity to increase your taxes and will slap all money of regulation onto your business as if in a deliberate attempt to make you fail. At the end of your business cycle, you will find that you have not make the profits that you wanted to make in the first place yet your property will be in tatters partly due to the mischievousness of the people you decided to invite into your house.
