Here is a rundown of the buying process:
The forms requied are:
Agency Disclosure:Necessary for agent to have you sign this disclosure before proceeding with helping you with any RE contracts
Residential Purchase Agreement: This is the offer detailing your offer price, who pays for what, etc.
If it is a short sale, there will be a short sale addendum.
If it is a bank sale/foreclosure, the documents may vary depending on the bank.
Along with the offer, the agent will most likely need to also submit a copy of your Earnest Money Deposit check, loan pre-approval, bank statements or other statements showing you have the necessary cash to close. Sometimes, your FICO scores will also be necessary.
After getting the offer accepted, including any counter offers made in the process, there will be lots of disclosure, etc during the escrow process.
