I’ve never heard the tip to create your own website when you have a home for sale. I also have never heard the tip to keep an eye out for “For Rent” signs to in order to look for more homes for sale. I’ve heard that it’s a good idea to find homes for sale that have been on the market for a while because there’s more room for negotiation, thanks for the tips!
A really rough guideline that alot of spot-lot developers use is that the land should be somewhere between 10 and 15% of the sales price of the home. So, if the homes on ten acres were selling for $1 million, the developers were likely paying $100-150k for the lots. The home on your lot would likely sell for substantially less given the smaller lot size, so expect less for the land sale.
Other options to consider are selling your land with owner financing which makes it easier for people to afford. Trying to find cash buyers can be difficult depending on your asking price and banks don't typically want to lend on vacant land. Also, if you have land you want to sell in a hurry and you'd like to get cash for it there are a number of wholesale land buyers that make be interested in making you a cash offer for your land.
Your buyer profile can depend on what type of property you are selling, whether the land has been developed already, its location and market conditions, among other criteria. Is your likely buyer an individual looking for a lot for a new home? Or is your buyer going to be a builder or developer looking for land for their next project? Or is your buyer some combination of those, or someone different altogether? There may be different buyers for finished lots, rural acreage or a parcel of suburban land in a thriving new home market.
