To sell or hold on to my duplex?

[Matthew Thorp]

I have a duplex that generates $2800 a month total. My expenses are $1800 total a month. I have a loan of $270,000 at 4% for 30 years. I am trying to figure out my ROI and if it makes sense to hold on or to sell. And if I am to sell what price I should list at. Thank you.

So you put no money into the deal and the only expenses you have are $1,800/month which includes everything?  If so and your cash flowing $1,000/month with no other expenses other than the $1,800 you mention above, I would say you hit a grand slam and should definitely keep as an investment.

I feel like I might be misunderstanding something though.
