Is This Duplex A Good Deal? - I'll live on one side...

[Steven Guy]

Hi All!

I have never invested in real estate before. In fact, I've only rented until now. I run other successful businesses (not real estate related) and I want to start investing in some more passive income. I'm single and still pretty young. I also have a lot of liquid cash to invest right now and I'm interested in a local duplex. I will live on one side of it and rent the other out. I'm also assuming I can get a pretty good mortgage rate because I have 800+ credit score.

But here's the numbers:

• Asking Price: $450,000
• Annual Gross Income from renting both sides of the duplex: $35,340 (keep in mind this will only be $17,670 because I'll live on one side)
• Taxes: $5,153.00
• The place was built in the 80s so it's not too old (or too much maintenance).
• The place is in an area where I'll always have renters (so little vacancies).

What do you think? 

Is this a good deal? 

I'm only really thinking of the one side of the duplex as an investment since the other side will be my residence. 

If the price is too high, what do you think I'd have to negotiate this down to to make it a good investment?

Thank you so much for providing any help/suggestions possible!
