Is this all I need to concern myself with, the water in the area seems healthy, and no 'news' of 'Gas Leaks' in the news. 

But, it's not more than they are capable of paying.Here are some example of the suffering costs of success:If you suffer the cost of disciplined spending and investing habits, you will have peace of mind and an early retirement.If you suffer the cost of daily exercise and nutrition, you enjoy a great physique and an exception quality of life.By suffering the cost and inconvenience of going the extra mile for your clients, you will enjoy bigger commissions and increased opportunities in life.By suffering the cost of preparation and doing more than what's expected, you will enhance your reputation, expand your opportunities and increase your social capital.The price of success is temporary discomfort.

Or teaming up with other investors who need some rehab cash (albeit more prone to risk than online savings)- this would give you first hand experience in the REI world & provide a healthy return.Lots of fun ideas out there, just requires time, patience, & discipline- since we're practically neighbor's- feel free to pm me if you ever want to meet up and chat real estate.

It's not a down market yet but it's not as healthy as it once was. 

I have committed to a healthy marketing budget this year and have a few strategies lined up including direct mail.  

You need to develop healthy personal habits and work habits (I struggle with both).

The more you put out the better response u will receive but with a newbie like me wheres the best place i can start with a healthy market ?

Besides the healthy returns and low entry points, it's very satisfying to fix up a "warzone" house.

While these large purchasers might make it more difficult to find deals, overall, they bring the values up, helping under water homeowners get out of trouble and making for a more healthy market.

If property values goes down in the next few years but the property continues to maintain a healthy positive cash flow do you really care what it appraises for?
