Is it worthwhile keeping the duplex

[Mark Vesu]

All, I am leaning more towards selling my Duplex.  Here are my numbers:

After all the expenses, my take home is around $1600/mth. The property appreciation is around 4% / year. This is low as compared to SFH. Not to mention all the headache dealing with the tenants, repairs, etc.

If I sell the property, I will make (after cap gain tax @15%) around $550k. If I invest that amount in a good dividend paying ETF @8% pa I will make $3600 per month.

Am I missing something?  Appreciate feedback from the gurus.  Thanks in advance.
