Contacting Vacant Home Owner

If you come across a vacant house that isn’t listed as being for sale, would you include an offer price in your letter/postcard to the owner? Or just send them a personal letter inquiring if they would be interested in selling?

no. always let the seller say what they want first. they may be willing to accept far less than what you’re willing to pay

just send a post card or letter stating that you’re interested in buying it
