I plan using the agent to help me sell the property, which I hope will give them an incentive to help me.Find a contractor to give me an estimate on the repairs/rehab of the property.Once I've collected all of this, I plan on reaching out to private lenders and providing them with the information I found on the property which I HOPE will be reinforcement for them to invest their money in the property...
