Seller felt insulted on the offer and hang off

[Le Jia]

All - not sure how to move forward with this situation. 

So I have a seller who is interested in selling the house. The property is in a decent place. The market price goes about 500k. He is expecting 550k according to him... (The bigger (500 sq.ft bigger) unit sold for 550k which was completed remodeled). I offered 370k and envision 60k remodel without looking at the house. The seller wants easy transaction, no agent fee, and MLS pricing but doesn't want to see the house myself or repair needed. After I provided my more than MAX offer... he just hang off and texted saying I will not call you again...

Should i move forward with this guy and keep asking. It sounded like he just want an offer in my opinion and to compare with others. Now i am writing this, I felt i shouldn't follow up with him anymore. lol but I really want his two properties.
