Should I take this deal or keep it moving?

[Shakia Morrison]

I accidentally offered too much for a wholesale deal. They were asking 299 and I offered 270. They responded that they would consider 280. I'm going to offer 275. I am wondering if I can still make a decent profit after all the fees associated with closing. The property is a 2100ft 4 br home with attached commercial space and finished basement. It is located near the beach in a decent area of New Bedford MA and the seller says it can be made into a duplex if you don't wish to use the business space. I also kinda just want to go through with it just to learn the process and I am anxious because this would be my first deal. It is simple, no realtor involved and I already have a title company and contracts lined up. What do you guys recommend ?
