Cash buyers shouldn't be a worry. What I recommend to some of the buyers I am working with is before submitting an offer to write a quick biography about themselves and a description of why they like the property, to explain what characteristics about the property and or neighborhood that compelled them to write an offer for that property then this information is presented with the offer being made. Generally once the offer is presented to the seller and the terms of the purchase makes sense such as price and net proceeds for the seller then the seller will generally will focus on what or how they can identify with the buyers if your situation is compelling or the seller identifies with the buyer then generally there will be a deal.
Another recommendation would also be to have the agent you are working with present the offers personally to the listing agent and assure the agent that you the buyer and the agent are in for the long term and will available during the entire transaction.
One more nugget would be to study the current market conditions in the neighborhood your planning the purchase, once the property is identified than write the offer at listing price or higher depending on the circumstances at the same time making sure that you safe guard against any appraisal issues unless they are negotiated prior to. I wish the best of luck, if you have any additional questions please feel free to ask, the answer to your questions are free.
