I would focus on established markets that are still showing growth and have more than just one draw.Taking my main market of Tampa Metro as an example - There is more than just beaches, you also have MLB/NHL/NFL + Spring break and MLB Spring training, aquariums, golf, casino, new downtown development, and a lot of business travel.You want to avoid markets with just one draw, as if something happens to that draw, you will be hurting for who knows how long.

The profitability of the investment may also be increased by arranging for a balloon payment, extending the repayment time, or negotiating a reduced interest rate.Thirdly, consider the advantages of purchasing the property using seller financing in the long run.

For my problems over the past few years I would strongly suggest that you do drive-bys long before and long after the scheduled inspection.
