@Ryan D. am I understanding this correctly. Your wife is an agent and you're trying to get advice on how to sell a home? Forgive me, this will sound harsh though text. This is absolutely scary lol.
It scares me because there are people out there that will hire agents who do not know how to sell a home, and the poor seller will lose thousands of dollars because an experienced buyer agent can sniff these things out and clean them out, which is good for the buyer. Not so great for a seller.
I understand it is not your wife's fault, it's just something scary I see all the time. And if provokes emotion every time :)
Bullet #1: Just because it's typical doesn't mean that is how it has to go down, what kind of negotiator are you if you're already giving up cash before you even have a buyer.
Bullet #2: The reason those houses went under contract is that they were on the MLS. A common mistake by FSBO is thinking if I post in on craigslist they will come. No- they will not come.
Bullet #3. Get a plan together so you can calculate the complete cost of the sale. Most FSBO price the home to high, and believe that if they post it on craigslist the buyers will come, and that is going to have you paying for housing for a very long time.
Bullet #4 A high percentage of home sales use the state approved fill in the blank contracts provided to realtors by the association they are members of. Why would you want to use anything else? Of course, you can get a lawyer but that adds more expense to the sale.
I would suggest selling it on your own to save the commission but have your wife seek out a more experienced agent to mentor her through the process.
