How do my numbers look for this property in Baltimore, MD

[Tom Saysithideth]

Hello BiggerPocketeers,

Looking into a potential property for rental income cash flow. Here are some numbers I put together:

Property Cost: 300,000

Mortgage: 1250/month

Rental Income: Unit1: 850/month Unit2: 900/month Unit3: vacant

Property Tax: 5800/yr

Property Insurance: 60/month

Vacancy: 63/month

Repairs: 100/month

Cap Ex: 100/month

Down Payment: 10,500

Closing Costs: 10,000

Concerns arise about house hacking to get an FHA loan, and staying for a year not making any positive cash flow. This is a 3 unit multi-family, and estimating the 3rd unit will rent for 800/month once I move out of the FHA loan. Interested in hearing the forum's feedback on the numbers and property.

Thank you,

Tom
