The first question I would ask is if they have any experience working with investors. (When they say yes, ask them what type of investors, and how many they have worked with)
It might also be a good idea to ask the agent what their process is or how they work with investors (agents with more experience will likely have figured out a different way of working with these types of clients as it is not economically efficient to work with them the same way as a "typical home buyer"
You will want to make sure the agent is a good resource for you so I would also ask the agent if they have any good lenders they can recommend for the particular strategy of investing you are trying to do. (If they only recommend traditional finance options- move on). Also ask if they know any good contractors or remodel companies that they recommend.
As to your last comment about considering this line of work and advice about providing value on the field I have 2 comments:
First, perhaps consider working for/with an agent as a marketing assistant or something of the sort. This will give you access to their data systems and tools with out having to get licensed or have a bunch of restrictions placed upon you. It is ok and maybe even better if that agent does not necessarily work with investors. Then you can help this agent find solutions (or be the solution) for their customers that do not have a market ready home to sell.
Secondly, if by bringing value to the field you meant the agents, then you will be a much better client for your agent if you have a clear picture of what you want. The more specific, clear, and focused you are on exactly what you want the better the agent will be able to serve you. The following are some questions I typically ask when an investor calls me looking for an investor friendly REALTOR:
What type of investor are you (Wholesale, Buy & Hold, etc)?
What is the maximum you want to spend (this is for search parameters)?
How do you plan to finance it? What kind of ROI are you looking for?
What type of real estate do you want to purchase (SFR, Multi-family, Mobile Home, etc)?
What are you looking for in a property (#of bedrooms, sq.ft, age of home, etc)
What area do you want to purchase in?
What current processes do you have for finding properties and getting them under contract?
Are you willing to sign a Buyers Representation Agreement if we decided to work together (if the agent sounds like they check all your boxes the answer should be yes :)
I hope that answer was helpful! Please feel free to DM if you would like to discuss further or are interested in purchasing any investment properties in North or Central Texas.
