@Cory Lucas unfortunately it sounds like he does not have an interest in helping you search for for BRRRR property.
As both an investor friendly agent and investor I can see both sides. From the investor standpoint: before I was licensed I was sure to hire an investor friendly realtor who owned investment property. One... he could provide his insights and leverage his experience and two, he knew how to navigate the market. I would recommend you look for the same. Someone who owns investment property can speak the language and close a deal out for you.
As an agent now...I will provide an agents standpoint and please do not take this the wrong way... just devil advocate.
I do not know your market but if it's anything like the East Coast finding possible flips/BRRR's on market right now is nearly impossible... numbers just don't work. Working with first time flippers can be challenging because of the lack of experience and you end up showing 10-15 houses before you can get one under contract. Then you have to go back 2-3 times to that same house because they have to get quotes from their contractors ect. All the houses you are showing are relatively inexpensive because they are 'flip' properties and need a good amount of work. If they are a decent agent they are most likely working with 7-10 clients at one time and their time is limited. Just from a time/money standpoint, it doesn't make sense to devote all your time and energy to a small commission check. And if you are doing a BRRRR and not flipping it... they know they will also not get the sale on the back end.
Now that doesn't excuse someone to act the way this realtor has but it could be what's going through his head. I would have an open conversation with the realtor and be honest. It could just be as simple as it's just not working out and you move on. If that's the case, when you start looking again make sure to ask a lot of questions to your new realtor. Do you work with investors... do you own property have you worked with flippers before ect ect. When you find someone make sure not to waste their time. Run your numbers to the best of your ability before seeing the house. Schedule your contractor to join you the same day as showing. When your running your numbers be realistic. If you keep sending low ball offers it will become frustrating for the realtor. Explain that you are in this for the long-term (if you are) and you want to keep using the same realtor and build relationships ect. Hope this helps provide context from both sides.
