@Thomas Franklin thanks a lot for the tips and advice. I will use those questions you recommended to filter the right realtor. I really like the strategy of focusing on the county/city with the greatest number of sales in the last 90 days.
I had a realtor investor help me identify the first property and he was candid in advising me to try to list and sell it myself first, to save on fees. I know realtors say they can sell faster and get more etc., but I think I did good. I was able to list it on Zillow myself and on MLS for $99 through a brokerless listing, and was able to sell it without a seller's agent, but did pay the buyer's agent. So, my realtor made a commission only from the first deal, not the second one, which was not proportionate to the time he spent, therefore now he proposed working on an hourly rate for identifying the property. That does not work for me as I do all the research on the internet to filter the properties, that he would then quickly filter further, show me the homes and help decide if it was worth pursuing . Now I have reached out to a few realtors that were the seller's agent for properties I filtered, and asked them to notify me if they see a good flip opportunity, but I I do realize they would have the seller's interest in mind.
