Thanks Quin, I would like to say that I have had an excellent support from you through out the process. You are detailed oriented, prompt in responding to our emails and provided a professional advise. This is an excellent program and you are representing this program very well.  So Thanks a Lot!      Definitely, if I come across anyone who is planning to explore the market (sell or buy) I am going to refer them to you.

Shannon and I would like to thank you for all your hard work on getting our house listed, and for handling the back-and-forth of offers, requests for showings, and your professionalism. We honestly could not have done it without you, and will be forever grateful. I’m glad I came across your services all those months ago, and would recommend 4Sale to anyone!

Should you need a reference, quote, or anything else from us please feel free to reach out.

Warm regards,

Shawn & Shannon in Aurura

Dear Quin,

In my lifetime I have purchased and sold 9 residential houses and the most recent one I sold using your organization was without a dought the smoothest and easiest transaction I’ve had! Better yet I saved alot of commission fees as well. Thanks for providing such a great service.


Jim in Bloomingdale

Having been very satisfied with your flat-fee listing program some years ago, we were delighted to find the service was still available when we came to list our condo in 2009. Once again, we couldn’t have been happier. The listing you provide on numerous websites for a flat fee is extraordinarily good value and highly effective in attracting potential buyers, But what truly sets 4 Sale Realty apart is your helpfulness and sound advice throughout the listing and negotiation process, at no extra charge. Your friendly responsiveness is rare not only in the real estate business but in any profession. We would wholeheartedly recommend your service to anyone. Thank you so much.

Being a lawyer myself, I do feel everybody needs a lawyer to close, for a couple hundred dollars you get an experienced attorney to look over your
shoulder as you sign sheet of paper after sheet of paper. Do you need to spend THOUSANDS on a real estate agent, Heck No!. I decided that for $500 it was worth it to try out this listing service. It was quick and easy to list my property, my agent answered ALL of my calls promptly. I had 12 showings in three days and signed a contract on day three! And just so you don’t think I priced my house to low, the buyers tried to get a mortgage for over asking price and the bank said no, the bank appraised the house at exactly asking price. I SAVED $7500 on commission. I would do it again his way in a heartbeat.

To whom it may concern,

My Name is Tasha Mosley-Brown, and I write this letter on behalf of Mrs. Jackie Grieshamer. I had the pleasure of meeting Jackie in the summer of 2010, she was assigned to me to help sell my property as a short sale. Upon meeting Jackie she was very courteous, polite and professional. The short sale process is a lengthy, aggravating and tedious process. My house was on sale for a while and then in Nov 2010, I received an offer and the roller coaster ride began….Jackie rode that roller coaster with such ease..she was the middle man between me and the bank…She stayed on top of all the communications, paperwork, faxes and all necessary aspects of this process… she was great through this whole ordeal…very reassuring..Jackie was always ahead of the bank, she could anticipate what they would need and then deliver….I finally closed on my house in Feb 2011…I loved working with her..I would recommend her to anyone interested in purchasing or selling a home…If I ever have the ability to purchase I would have Jackie as my Realtor…I would highly recommend her to any one looking to buy or sell…I met Jackie as a stranger and now I consider her a friend…..I wish Jackie all the luck in her future in the realty world….Thanks Again…:)

Your Friend,
Tasha Mosley-Brown

Dear Quin,

I am writing to let you know how appreciative I am of your professional, efficient, and kind service. Your competence was so reassuring. Everything you said you’d do, you did (and promptly as well). This level of honesty and competency is not always found in the business of real estate. Your advise was “right on” and your manner was so compassionate. All the best wishes and a huge Thank You!

Bill & Gretchen, Indian Head Park

I didn’t know what level of service to expect for the flat fee I paid. However, throughout the process Quin’s service continually exceeded my expectations. Quin was very accessible for questions (of which I had many). He usually picked up the phone on the first ring and if he wasn’t available, he returned the call very quickly and with good advice. I dealt with a lot of buyers’ commissioned agents during the process of selling my house and in my opinion, Quin provided much better service to me than those agents were providing to their clients. I am a believer.

Pat O’Malley

Quin, thanks for all the help with our FSBO listing. You were fantastic to work with from start to end. You have the best flat fee MLS listing service around. Thanks again for all of your support.

Joanne, South Elgin

The scheduled closing date is xx/xx/xxxx and it was all by owner – no realtors involved but you. We did have tremendous traffic with realtors and I’m sure your help in getting everything on-line and the addition of the virtual tours helped tremendously. We averaged one showing per day and sold it within a month. It was a pleasure doing business with you.
Dave & Beth, Downers Grove

Quin O’Brien has been an unexpected help in the listing of our home during this past year. While I connected with Quin through a third party, his service has been invaluable. The advice Quin provided has far exceeded my expectations, and frankly what I thought I was paying for. Quin is so much more responsive than other realtors that I have encountered. And He has proven his integrity through the advice and the service he provided. He is easy to talk to and has always been able to explain a procedure, a strategy, or a thought process in a way that has helped me to move forward. I am sure that he can do the same for you

Rich and Laure, Oak Lawn

I am happy to say we closed on our house on September 5th. Finally. A sincere Thank You from both me and Dana.
Your help and support throughout the whole process and multiple listing periods was testament to the fact that there are still great
real estate professionals out there. Your service and personal attention was refreshing in a rather difficult time for us.
Thanks again and best regards.

Alex & Dana, Hoffman Estates

We finally closed today on the sale of our house. Maureen and I just want to thank you for the major part you played in getting our house sold. We have never met you face to face and you have never seen our house other than on the MLS listing, however, you always treated us as if we were your only client. You answered all our calls in a timely manner, you answered all our questions and gave us exceptional advice. We will forever be grateful to you and have already recommended you to a couple of people and will continue to do so in the future. Thank you, Thank you, Thank you.

Jim and Maureen, Cary

Just to let you know, we did close today, thank goodness! How nice to have that behind us!

I just have to tell you, we have bought and sold a number of properties with other full-service realtors, and you are definitely among the best. Even though we used your “by-owner” service, we always got your very best, prompt service and you were fantastic at answering all of our questions and getting things done when we needed them. You are exactly what we were hoping for when we signed up for the “by owner” MLS service, which truly was all we needed on this property. Thank you again for everything — you can be sure you’ll be hearing from us when it comes time to sell again!!

Dawn & Gary, Carpentersville

I will most definitely recommend you to others selling their places – you were so helpful and responsive. Thank you again for all your help!

Kristine, Chicago

I’ll be happy to sing yours and the FSBO praises to the sky. I will tell you – I am totally amazed how easy you made this for me and better yet – yes just like the commercial I saved $5500 in commissions.

God bless you and thanks so much,
Bonnie, Wheeling

As far as your program, I am extremely impressed with your professionalism and have already recommended to few. I am confident that they will use you very soon.

Aziz, Morton Grove

4 Sale Realty is to Real Estate, the way CarMax is to the Auto industry: An honest, easy, and inexpensive way to buy/sell the same house for thousands less & YOU POCKET THE CASH! I received exceptional support from Bob Sharpe and I will never, ever use a full price broker again.

Jeffrey, Hanover Park

Send me some of your business cards. I’ve been telling everyone in the OR about your fabulous services!

Sara, Aurora

I can’t tell you how helpful you have been through the entire process. We have been very satisfied so far and will not hestitate to recommend your services to all of our family and friends!

Nate & Jolene, Lake Villa

Thank you very much for all your help. If I know anyone selling their house, I would recommend them to you.

Diann, Addison

Thank you for all of your help and your professionalism throughout this process…I truly appreciate it.

Mark, Carol Stream

Thanks for your help with everything. We are huge fans of the flat fee listing and enjoyed working with you. We are spreading the word and will be sure to give your name to friends planning on selling in the future.

Greg & Katie, Evanston

I would definitely pass your information along! Your attitude is just superb and very friendly. I know that may have nothing to do with how quickly our property sold, but customer service is so important these days and you definitely meet and exceed my expectations! At a time when I could be a wreck with worry, you answer questions thoroughly and politely making the whole experience more pleasant. Thank you so much!

Lynette, Oak Forest

I would like to take this opportunity to thank you for all your help in the sale of our home. I find it refreshing to do business with a firm that conducts itself in such a professional manner. Your firm was quick to react to our questions and needs and your follow-thru was complete.

Robert, West Dundee


Working with you has been a real pleasure. Your level of service and attitude are awesome, I will highly recommend you to all of my family and friends.


Sonny, Lake Bluff

We are telling EVERYONE about your wonderful service. This was so much better than going with an agent and having to pay him/her the extra commission. We are only paying the realtor who actually sells our house. We were able to do whatever marketing our agent did, and to much better avail. We were listed with him for almost 10 months and went through an horrendous experience. We sold in about 60 days (in the worse time of the year also) and got more showings in 60 days than we did in 10 months with the agent. We also had a little leverage with the selling agent. After all, we did not have an agent and did need one to get into houses to buy.

If we ever sell again, this is the way we would go. It’s the best of both worlds!!!

Marianne, Hoffman Estates

Hello Quin. Yes, we closed yesterday. Thank you for your excellent service and for helping me save a good chunk of change. You can be sure that you will get referrals from me.


Bob, Chicago

Thank you so much for all of your help in negotiating the sale of our house. You have been great at returning calls as well as very professional in handling the contracts. I will refer you to other friends that are planning on selling their home on their own.


Suzy, Naperville

Thank you for all your help during our house sale. We especially appreciated the assistance with the contract negotiation. You have an excellent flat-fee listing product and I am very glad this option was available to me for this house.

Larry, Palatine

Hi Quin!

Just to let you know we are very happy with our service. Thank you so much for all your help. The closing went smoothly. I have passed your info
along to a friend in need.

Thanks again for your prompt service and friendly attitude. You make me want to pay you more 🙂

Lynnette, Oak Forest


This was my first experience with FSBO, and I was especially concerned with whether it could work for a downtown condo in my price range. I had over 40 showings in an overbuilt market, and was pleased with the results I received. You were highly professional and responsive whenever I needed you, even though your revenue was modest.

In short, you personally made this experience pleasant, and the FSBO process worked very well, saving me the entire Listing Agent commission of
approximately $18,000.

I would highly recommend any seller utilize FSBO, but would especially recommend you as the FSBO broker.

Thanks again for an excellent experience. Please feel free to use this testimonial any way you wish.

Dick, Chicago

We liked the program, the way you handled our listing, the responsiveness to our questions and the service that you have provided. Yes, we would recommend this service to future homeowners who are considering selling their property on their own.

Todd, Chicago

Thanks for all your help. You were very pleasant to work with and always very helpful. We will be sure to refer friends to you.

Thanks again,

Julie, Schaumburg


We have been very impressed with the MLS program and with your energy, involvement, knowledge and attention to detail. We will certainly refer you to anyone seeking assistance with real estate. We’ll stay in touch.


Don, Naperville

You are the best man!! Trust me, I got a deal from a passer by and will not have to pay any commissions to anybody. But just doing business was a
pleasure and well worth the $450 bucks. Be assured you will get a lot of business from my friends.

Sachin, Lombard


This is the fifth home I have sold through you and I would not think of doing the next one any differently. Your service is simply amazing and you manage to do it all for a very minimal fee. The traffic through the homes have been great, clearly an indication of how you wrote the advertising. Each home sold in less than a month and the last one in less than a week thanks to you staying on top of things and some pretty effective negotiating. Please use us as a reference if you ever have the occasion.

Thank you,

Les & Maggie, Deer Park

No need for the commercial, hands down your are our favorite realtor to deal with. Next time a friend of ours is selling a place we will be sure to pass your info along. As for us hopefully we won’t be needing to move for a long long time.

Thanks again,
Mike, Westmont

Dear Quin:

Words can not express my sincere thanks & appreciation for all you have done for Suzanne and I. We will not forget all the kindness you have extended to us. I hope over & over that I get the opportunity to recommend you as a Realtor. You are great but more important – Honest.

Marilyn, Mount Prospect


Hi Quin. We just wanted to tell you again how much we appreciate everything you did and all the help and support you provided. I would urge anyone looking to sell their property to contact you. If you ever want or need a testimonial, please feel free to use this email.
Happy Holidays!
Barbara and Rich, Chicago


We have been more than delighted with this transaction–quote us in your testimonials as saying so! You’ve been so helpful each step of the way. We’ll be sure to tell others!

Thanks again, Quin!
Betsy, Palatine



I just wanted to say thank you for all of the work that you did for us. We have already referred people to you that may sell their homes in the near future, because you really did provide excellent services and were always on top of things.

We also appreciated your advice as things came up during the sale process.

Next time we get ready to sell, we will be calling you.

Thanks again, and please let us know if you need any testimonials!

Lisa & Robert, Schiller Park

Thanks, Quin. I will definitely refer your services to friends and family. I have to say that when I signed up for FSBO, I did not expect much if any interaction with the listing agent. You have greatly exceeded my expectations. I truly appreciate your quick response times, advice and professionalism..you made the process very easy for me.

Thanks again.
Rusty, Chicago
