You look good based on your credit (677 mid score) and your $30k down payment.
Based on that purchase price and your down you will be at $90k to $70k loan amount. I don't see any problem necessarily with qualifying.
The only missing piece is your income. At this point, I would love to work with you and get you pre-approved and then get you out looking, perhaps with Ute Ferdig, who is a local market expert.
I will get you pre-approved for what you qualify for and then you can decide if you want to go lower on the purchase price, as the market is very competitive especially in the price range you are looking at here in your post. My cell is 916-813-4003; email email@example.com
