The use of a title company is highly recommended, even for a lot. Unless there is a title search done on the property there is a clear title. For the money it will cost for the service, it will be worth knowing you are not embracing the debt of someone else.
To get clear title you must have a title company do the closing.
The Deed is the only document that must be recorded.
1. Zero documentation.
2. A receipt for the money paid.
3. A receipt for the money and a deed from sellers to buyers.
4. A receipt for the money, a deed from sellers to buyers, verification of payment of property taxes.
And so on
The question is how much do you trust the sellers to pass clear title and how much "insurance" do you want that you will get marketable title for when you want to sell. If you want to see a sliding scale of the bare minimum to the full and complete, call the title company, tell them your goal, and see what they offer.
An entire industry exists to support the transfer of real estate. This industry grew out of a different industry: fraudulent sale of real property. A knowledgeable and experienced person can do without a title company when buying real estate and not get burned. An inexperienced person is inventing the process as they go along and has to consider whether the advice they get on a do-it-yourself closing is based on an someone's incomplete understanding of the pertinent underlying facts.
