If you are looking for your first deal in three separate locations and using agents in each one and they know that, they will first ask are you looking to and do you have the means to close in all locations. Because if not, you are going to be wasting two of the agents time. As an agent, in order to be comfortable with out of state buyers, I want to see a proof of funds and also know your plan for properties. I also want to use something like UberConference to make sure we have a good idea of how we both work.
You are asking a lot of agents who don't know if you will do 10 deals with them if it works or if you are looking for the best deal with 3 realtors and when you find it, you will opt out of the other areas. Running comps is not simple if done right, especially for investors. You want to know block values, foreclosure prices, market prices, this all takes time so you need to show the agent if you are intending on making this a business and how you are going to do it. Automated comps are not comps.
Any agent can put you on an MLS drip every morning, that's basic. In terms of all lowball offers, you have a much better chance of finding an agent to do this where you live. Being out of state and expecting an agent who you have never done a deal with to look at the properties for you, do all the comps, assess everything and then basically be responsible for your purchase, all tied in with low-ball offers is going to be very hard.
I hope this helps.
