420k for two A property duplexes

[Alison Lee]

I have a shot at two duplexes, four doors total that they're asking 475k total. These are A properties, and approximately 2-3 years old. Each door rents at $975 and all four have tenants. Taxes would be roughly $4,750 per year if bought at 475k. Insurance would be $1200 per duplex or $2400 total. Maintenance expenses would/should be small... 

Is this an attractive deal? I feel like I could possibly buy these for 425k. Thank you!
