I need mortgage help

[Zackery Smith]

I found a the Golden deal. 1000 sqft house 3 bedroom 1 bath. $70,000.00. The only problem is the bank wants 7,500 on closing cost and 20% down (14,000) payment. I only have 20k. The owner is willing to pay the closing cost but the bank said he can only pay 2% of closing since it's a conventional loan. Should I go to another bank or will all of them be the same? I don't get why it's not working out. It's so cheap! Please let me know what you think. I'm in Florida of that helps.
