First Deal - Analysis Please!

[Aron Teran]

I'd love some feedback on my first potential deal....prepared to ratify the contract. Details:

Duplex purchase price: $135,000

25% Down Payment: $33,750

Closing Costs: $4000 (projected)

Combined monthly rent: $1350

Annual Property Tax: $2260

Both units currently have month-to-month tenants

Assuming 5% each for vacancy, repairs, and capex

Will self-manage

$70/month insurance (projected)

30 yr mortgage @ 4.75%

Monthly Cash Flow: $371

NOI: $10,672

CoC ROI: 11.5%

This is assuming no issues arise during due diligence and the home inspection. Thoughts? Am I overlooking anything?

Thanks in advance!
