The only thing real estate agents and brokers do is get the buyer and seller together, and show up at the closing to get their cut. You've already done what the real estate broker's and agent's function is.

In most states, real estate closings are done by attorneys. However, in Floriduh it's normally done by a "title abstract company." It sounds like that's also the case in Oregon.

Attorneys usually sell title insurance, also. It's cheap and could prevent losing the whole property if there's something fishy with the title. The last attorney I used to sell some property gave me a deal because I bought title insurance from him.

You can save on property taxes by having the lots legally combined into one lot. If you want to sell it later, you can split them up again.
