Buying property privately
We are in a position to buy a property and we meet seller through a friend and they want to sell it privately and not through a realtor, I guess so that they can maximize their profits and avoid realtor commission. We agreed already on the price and they are in no rush to sell. One of the conditions of us being approved for a mortgage rate from the mortgage broker is to have purchase sale agreement. The seller ask us to prepare one. So few questions we have in mind:
1) Do we need a realtor to help us draft the purchase agreement?
2) If we go this route, Does that mean that we have to pay the realtor instead of the seller?
3) And roughly how much realtors charge for representing the buyer?
4) or Do we go straight to a real estate lawyer and have their services with them?
