Investors should not base their investment decision on yield alone but examine some of the key metrics described below. In most cases, higher yields are associated with a higher degree of risk. It is okay to deploy some capital into riskier plays but betting the house is asking for trouble.
Free cash flow yield is obtained by dividing free cash flow per share by the current price of each share. Generally lower ratios are associated with an unattractive investment and vice versa. Free cash flow takes into account capital expenditures and other ongoing costs associated with the daytoday to functions of the business. In our view free cash flow yield is a better valuation metric then earnings yield because of the above factor
Levered free cash flow is the amount of cash available to stock holders after interest payments on debt are made. A company with a small amount of debt will only have to spend a modest amount of money on interest payments, which in turn means that there is more money to send to shareholders in the form of dividends and vice versa.
Operating cash flow is generally a better metric than earnings per share because a company can show positive net earnings and still not be able to properly service its debt; the cash flow is what pays the bills.
The payout ratio tells us what portion of the profit is being returned to investors. A pay out ratio over 100% indicates that the company is paying out more money to shareholders, then they are making; this situation cannot last forever. In general if the company has a high operating cash flow and access to capital markets, they can keep this going on for a while. As companies usually only pay the portion of the debt that is coming due and not the whole debt, this technique/trick can technically be employed to maintain the dividend for sometime. If the payout ratio continues to increase, the situation warrants close monitoring as this cannot last forever; if your tolerance for risk is a low, look for similar companies with the same or higher yields, but with lower payout ratios.

Turnover Ratio lets you know the number of times a company's inventory is replaced in a given time period. It is calculated by dividing the cost of goods sold by average inventory during the time period studied. A high turn over ratio indicates that a company is producing and selling its good and services very quickly.
DebttoEquity Ratio is found by dividing the company's total amount of longterm debt (debts with interest rates that have a maturity longer than one year) by the total amount of equity. A debt to equity ratio of 0.5 tells us that the company is using 50 cents of liabilities in addition to each $1 dollar of shareholders equity in the business. There is no fixed ideal number as it depends on the industry the company is in. However, in general a ratio under 1 is acceptable and ideally it should be in the 0.50.6 ranges.
Current Ratio is obtained by dividing the current assets by current liabilities. This ratio allows you to see if the company can pay its current debts without potentially jeopardizing their future earnings. Ideally the company should have a ratio of 1 or higher.
Interest coverage is usually calculated by dividing the earnings before interest and taxes for a period of 1 year by the interest expenses for the same time period. This ratio informs you of a company's ability to make its interest payments on its outstanding debt. Lower interest coverage ratios indicate that there is a larger debt burden on the company and vice versa. For example if a company has an interest ratio of 11.8, this means that it covers interest expenses 11.8 times with operating profits.
Quick ratio or acidtest is obtained by adding cash and cash equivalents plus marketable securities and accounts receivable dividing them by current liabilities. It is a measure of a company's ability to use its quick assets (assets that can be sold of immediately at close to book value) to pay off its current liabilities immediately. A company with a quick ratio of less than 1 cannot pay back its current liabilities. Additional key metrics are addressed in this article "5 Interesting Communication Plays"

Important facts investors should be aware in regards to investing and REITS
 Payout ratios are not that important when it comes to REITS as they are required by law to pay a majority of their cash flow as dividends. Payout ratios are calculated by dividing the dividend rate by the net income per share, and this is why the payout ratio for REITs is often higher than 100%. The more important ratio to focus on is the cash flow per share. If one focuses on the cash flow, one will see that in most cases, it exceeds the dividend declared per share.

Notes

In our opinion there are better plays out there.
