Look at RNP, ALD, and PCC. I don't currently own any ALD, having sold all of my position, but am looking at re-entering it. Also, RMT (a micro-cap fund) pays out a generous dividend, though it sells for about a 5% premium currently. RNP is around a 10% discount, it would be my top choice. PCC is a hybrid reit and small business lender like ALD.
A number of Aimers are also in EAD, a high yield bond fund.
