I'd not ignore the divvie, and the monthly pay is a bennie, both in terms of the time value of $, and in terms of the limit in holding risk that generates.
But, I don't buy stocks "only" because of the divvie... rather than buying divvie stocks that I think have potential to enable gains as they appreciate in price more than in divvie bennies will allow from being paid to hold.
Here, the primary issue is that over the last few years the markets have convinced everyone that anything to do with mortgages or real estate is toxic... which results in the discount reflected in the price here that makes it yield almost 20%...
It is true that there is risk, of course... so you need to be aware of what the risks are, how they manage them, and how you should adjust your planning for changes in the market. Again, a reason to have a monthly payer...
If and when the mortgage and real estate markets improve, while rates stay tame, then the yield here will get smaller in relation to the changes in the market perception. If that takes 5 years to happen... well, they'll have paid you back most of your investment by then...
The yield might drop by half... giving you a double in share prices in that time ? And, if it doesn't... in relation to the risk, you'll still be getting paid and riding "free" shares relative to a non divvie payer?
