When searching for leads, which service do you recommend on using, Rebogateway, Leadsource, or PropertyRadar?

Go to your local title company and have them do a full blown search on the property.

That will help you focus your search.

@Greg Dorn - those are the properties that we are searching for as well.

I googled it but couldn't find.

Focus your market searches on keywords like "as-is" or "TLC" etc to get your listing down to what you are looking for.Know what your local lenders are willing to refi for after your repairs so you know what LTV to use.

Just keep searching! 

Later I was not satisfied with her home searching skills or Negotiation skills...I switched my Agent then the other Agent showed me a good home, we made a offer and also the sellers accepted it.Now somehow the other agent got to know it and saying that I had signed a Buyer Loyalty agreement for 1 year and harassing me to pay 2000$ to her for showing those 5 houses or else she wouldnt end the contract.

I'm happy to share my experience, so far, with the lot search and purchase process with other investors who are interested in this route.
