Did it in CT. Found an on-line service to get an MLS listing, which is key. If you are selling it yourself without an MLS listing, you're not reaching a huge number of the buyers - at least that's how it was a decade or so ago, and, whatever price savings you get from having no agent, you're likely to lose with lower price.
If you sell yourself, real estate agents will be mostly hostile, and will steer clients away from you, even if you're on the MLS.
Long story short, after being on the market for a bit, I ended up hiring a real estate agent.
I am a lawyer, btw, but I'd still hire a realtor to handle any real estate transaction if I didn't have a ready buyer. If you know the person to whom you are selling, don't hire real estate agents - they are unneeded.
In general, I've been involved with many real estate transactions for myself, and hundreds for clients. Here are the basic lessons I've learned:
Real estate agents, with some exceptions, work for the deal. If you tell them what your max or min price is, that will get leaked to the other side - use that to your advantage. Real Estate agents will hire blind, deaf, and dumb home inspectors who green-light deals. If you're selling, not your problem. If you're buying, use your own independent inspector. Use your agent as a means of getting in houses - use information they give you on neighborhood, school, and so on, but verify - don't trust them unquestioningly.
"Dual Agency" is a euphemism for unethically representing the buyer and seller at the same time so that the real estate agent can double up on the commission. It should not be allowed. Had one recently where I was representing the seller. Buyer had backed out. Agent was dual agent. Agent told buyer to fill out cancellation form, which Buyer did. But agent neglected to give Buyer the correct date by which that form needed to get back to him. Form came back a day late. When he called me, I said, "my seller keeps the deposit." He tried to argue that a good faith attempt was made to cancel. I asked, "don't you represent my client? Shouldn't you want him to get the money?" I guess not, when he realizes that his rear was on the line for the money.
Real estate contracts are almost always trash and easily voidable, particularly the one drafted by the national association of real estate agents. It's plain awful. Expect that any buyer can back out for a myriad of reasons. The deal isn't done until the check clears and/or you have physical possession of the house.
As a buyer, avoid rent-backs. Make sure the house is empty on the day you buy. Getting people out of your house can be a costly nightmare.
If you end up with a "settlement agency," and there is only lawyer at the table, you can consider yourself unrepresented. It's the same unethical scam the agents are running. There is ZERO way to represent a buyer and a seller at the same time. What if the seller tells the lawyer about a defect in the house that does not need to be disclosed by law? If you're selling, your absolutely should have your own lawyer to prepare the deed and attend the closing. If there is settlement agent and you don't hire your own lawyer when you are selling, that agent will get that fee. Hire your own, no extra cost to you, agent does not get the fee (but check the rules/laws in your jurisdiction). If you're buying, you absolutely want your own lawyer, if cash, but if you're using a bank, you're probably stuck using the bank's "settlement agent," who will likely tell you that he/she is your lawyer, but who has a massive conflict of interest because he/she gets most of his/her work through the bank. If the ca-ca hits the fan-fan, the lawyer will side with the bank.
I'm a DIY guy. I do everything I can myself, for the most part. I maintain a few exceptions, among them: 1. I don't move furniture - not my own, not my friends. 2. I don't brine/smoke/cure my own bacon/hams. 3. I don't do my own gunsmithing. 4. I don't weld. and 5. I don't sell my own real estate.
Realtors serve a needed purpose, as do real estate lawyers. My advice is to use them. Maybe we'll get to a day where we have a HouseBuy app and we can get rid of the agents and lawyers. We're not there yet.
