Thoughts on Doing a 1031 soon

[Michael Win]

I just purchased a duplex 3 months ago.  Bought for 169K, Loan left of 110K.  I would like to sell the duplex for 210K.  I am sure I can get this price as a duplex down the street in worse condition/lower rents just closed for right at 210K.

I want to do a 1031 and put the 100k down payment into a 4-500K property (financed) which should get me 2-3X better cash flow.

The numbers makes sense.  Sure risk is more, but I am not risk adverse.  Does this seem like a good strategy or should I just continue to collect my $900/duplex as cash flow?
