Too good to be true?

[Shea Spinelli]

At work today, a customer informed me they had a house for sale priced at 350k, they purchased in May of 2016 for 345k. It's in a premier neighborhood and they are wanting more room so they're selling. They told me they would take 242,500 for the house so they could move it. My realtor showed low comps at 295k. I'm putting an offer (wife consent first) on the home. I would like to purchase it and turnaround and list it for roughly 325k to move it quickly enough and net roughly 30k. Does this sound too good to be true? As long as we write in opt out clauses appropriately it's definitely worth researching. Thoughts? Should we buy and hold to rent? It's not a normal buy/hold neighborhood considering the area.
