Please help a newbie out - South Jersey analysis

[Yvette Chung]

Hi all! I have been a long time lurker and finally just acquired our very first rental property. It's a duplex in South Jersey. While i have tried to take everything i learned from BP I am hoping to leverage your expertise. Please let me know what you think of the following #'s.

Purchase Price $172,000

Cash put in (mortgage down payment + rehab/improvements) = ~$55,000

Expenses

Property Tax: $5100 annually or $425 per month

Mortgage P&I per month ~$560 per month

Insurance: budgeting $1000 per year

Utilities (sewer/water/garbage...etc) ~$165 per month

Vacancy: assuming 5%

Maintenance budget: $1500 per year

Income

Unit 1 = $1050

Unit 2 = $1200

Do these numbers look ok? Any considerations that i am blatantly missing? 

Thank you in advance!
