How else can we determine if a REIT is a good buy, other than looking at Dividend Yield, Gearing Ratio and how a company is doing?

For REITS these are the things that you can look at

Qualitative Aspect

• Sponsor

• Manager

• Location of properties

• Stablility of Country

Quantitative Aspect

• Gearing

• Cost of capital

• Wale

• Revenue track record

• earnings track record

• payout ratio

• occupancy rate

• Diversification

• P/B

As of now based on P/B reits are generally over valued

Hello! I answered a similar question previously in Seedly, but I thought the answer is worth reproducing below!
I helped to develop the investment framework for a Singapore-REIT-focused investment newsletter with The Motley Fool Singapore. The newsletter has delivered good investment returns, so I thought I can offer some useful food-for-thought here. The REIT newsletter was launched in March 2018 and offered 8 REIT recommendations. As of 15 October 2019, the 8 REITs have generated an average return (including dividends) of 28.8%. In comparison, the Straits Times Index's return (including dividends) was -3.1% over the same time period. The average return (including dividends) for all other Singapore-listed REITs that I have data on today that was also listed back in March 2018 is 17.2%.

The investment framework we used had four key pillars.

First, we looked out for long track records of growth in gross revenue (essentially rent the REITs collect from their properties), net property income (what’s left from the REITs’ rent after paying expenses related to the upkeep of their properties), and distribution per unit. A REIT may fuel its growth by issuing new units as currency for property acquisitions and dilute existing unitholders’ stakes. As a result, a REIT may show growth in gross revenue, net property income, and distributable income, but then have a stagnant or declining distribution per unit. We did not want that.

Second, we looked out for REITs with favourable lease structures that feature annual rental growth, or REIs that have demonstrated a long history of increasing their rent on a per-area basis. The purpose of this pillar is to find REITs that have a higher chance of being able to enjoy organic revenue growth.

Third, we looked for REITs with strong finances. In particular, we focused on the gearing ratio (defined as debt divided by assets) and the interest coverage ratio (a measure of a REIT’s ability to meet the interest payments on its debt). We wanted a low gearing ratio and a high-interest coverage ratio. A low gearing ratio gives a REIT two advantages: (a) the REIT is likelier to last through tough times; and (b) the REIT has room to take on more debt to make property acquisitions for growth. A high-interest coverage ratio means a REIT can meet the interest payment on its borrowings without difficulty. At the time of the REIT newsletter’s launch, the eight recommended-REITs had an average gearing ratio of 33.7%, which is far below the regulatory gearing ceiling of 45%. The eight recommended-REITs also had an average interest coverage ratio of 6.2 back then.

Fourth, we wanted clear growth prospects to be present. These prospects could be newly-acquired properties with attractive characteristics or properties that are undergoing redevelopment that have the potential to deliver higher rental income in the future. It's important to note that there are more nuances that go into selecting REITs, and that not every REIT that can ace the four pillars above will turn out to be winners. But at the very least, I hope what I’ve shared can be useful in your quest to invest smartly in REITs. To sum up, keep an eye on a few factors:

(1) Growth in gross revenue, net property income, and crucially, distribution per unit.

(2) Low leverage and a strong ability to service interest payments on debt.

(3) Favourable lease structures and/or a long track record of growing rent on a per-area basis.

(4) Catalysts for future growth.
