Is this a good deal? Or Not? Potential investment property.

[Thomas Lee Malpass]

Hi guys so I’m thinking about buying this property to live in and have as an investment in the future. It’s a 4 bedroom 3 bath 2600 sqft House. The seller is asking 600-620k for it. Which I think is a good deal for San Diego and with the same specs on houses in the area. It’s been on the market for 65 days and his original asking price was 689k do you think this is a good deal or no,
