Found a Potential Deal, Or is it?

[Keith Read]

I am a newbie here. I watched Brandon Turner's webinar live last night and as part of my commitment to this new career I started searching for some rental properties. I found a property and ran the Rental Property Analysis. The numbers look GREAT (based on what I learned last night); but would love some fresh eyes before I make an offer.

A little background - I signed up for Than Merrill 3 Day Course and attend later this month. During my Due Diligence; I came across BiggerPockets; I signed up with a Pro Membership and have spent the last days listening to podcasts and learning the site.

I would love someone with experience to let me know if I am doing this properly and should I pull the trigger. I still have a lot of ducks I need to put into a row.

Here is the deal:

Duplex - 2 Tenants
Asking Price: $114,900
Monthly Income: $1,300
Monthly Expenses: $905
Annual Taxes: $748
Monthly Cash Flow: $395
Cash on Cash ROI: 18.24%

I obtained these numbers while utilizing the Rental Property Calculator.  What am I missing?  Based on these numbers it appears that this property is a good opportunity.  Looking for advise from experienced Pro's.

Thank
