First investment property 3 unit

[Mike Cols]

Have been lurking on the boards, videos, and podcasts for a while have ran the numbers posted below. Looking at a couple different properties but this one in my opinion has the most potential. First floor unit has already been remodeled. Second/third floor need some work. With the work being down I am considering starting my offer %15-20 below listing. Can anyone give me their input on this deal. Along with the best advice for a first time landlord. I know screening is a top priority. 

List price: 160k 

Income:$2625

Expenses: $1375 + or -

P&I: $526

Taxes: $266

Insurance: $83~

Water/sewer: $200

Vacancy: 10% $100/month

Capex: $100

Maintenance: $100

Property management: $0 myself/Fiance was assistant property manager 5+ years. 

Cash flow: $1250

Assuming we agree to a price in the middle these numbers could vary. 

$28k down

$7k closing

$ 5k in rehab

Leaves me at a ROI of 37%

Even though the numbers all make sense in a perfect world still nervous about this as it is my first property. Would I be crazy not to jump at this?

Thanks in advance!
