Good afternoon everyone, I am a resident from Utah and i just found a buyer to sell my townhome rental to. I'm actually at a lose of what to do now. We have an agreed upon price with me paying for closing costs but I want to have everything in writing and get the process going for their lender to get an appraiser. I'm completely at a lose of how to actually sell my home. Any help here would be greatly appreciated. Thank you ahead of time.
