The population has been growing here year over year over the last decade, it is home to The Ohio State University which has over 50,000 students that live here along with those that visit, and it also holds a diverse range of young professionals and traveling nurses to fill the demand of the multiple business corporations and hospitals stationed here.

You will find others who promote a 1% strategy (if home costs $150K then must rent for $1500/mo), but my strategy is based on return and risk.

I would bet on cities with decent past and projected job growth. if the economy enters a correction, people will stay/flock to cities where there's jobs. there were some good cities already listed above but you'll also want to check that there's a diversity of economies, that it fits within what you have saved capital wise and have some local investors/connections already there who can help you out with building your team. 

In some instances, legal regulations prohibit people from carrying out certain tasks, such as administering life-saving support, that are considered morally permissible actions.FULL ANSWERSome laws generate few negative responses, as their intent to protect and promote the safety and well-being of the public is virtually indisputable.

On the plus side, it is added value in the future sale of a property, and having such a system is always promotion value in a potential turn-key sale of the property, as in I would promote the value of it.  

Make sure you fully understand your market.I strongly encourage you to listen to the Denver real estate investing podcast by Chris Lopez and put on by Castle and Cookthe promote Joe Massey as there mortgage guy and he puts on lots of in depth classes on best mortgages to use and how to break into the Colorado market.

I'd say as long the market supports good indicators such as pop growth, employment diversity, low unemployment (compared to national), job growth, etc., those will be the place to look. 

Come up with ways to promote longer term leases.
