Would you do this deal?

[JJ Buckner]

Hey Biggerpockets,

So I have been actively looking and analyzing deals for awhile now and think I may have found one worth going for. This will be my first deal and wanted to see what some more experienced investors thought before I pull the trigger. Below are my number's:

Duplex in Lee's Summit, MO (suburb of Kansas City)

Purchase Price: $135,000

Cash Down:       $32,000 (20% down plus est. of $5,000 closing cost)

Est. Rent:           $1400 (2 Units at $700 each)

Mortgage:          $717.54 (Including taxes and insurance)

Vacancy Rate:    5%

Repairs/Main:     5%

CapEx: Already have an emergency fund in place, so didn't include in calc

Cash Flow/month: $472.46

CoC Return: 17.72%

Cap Rate: 8.58%

Again, this is my first deal so if I am doing anything wrong with my calc, would love some advice! I feel the cash flow is to good to be true based on other deals I have been looking at. Let me know what you all think.

Thanks in advanced,

JJ
