Closing a real estate deal involves a fair amount of work and attention to detail (and of course, there’s always the chance that you could do something wrong). With a property like what you’re describing, the value that a professional closing agent brings to the table is a pretty easy thing to justify spending money on. In Virginia, I believe either an attorney or a title agency could do the job (but this kind of thing varies from state to state, so you may want to ask a local real state agent what they recommend).

The one technique for how to sell a piece of land that is the same for home sales is using imagery to help buyers get a feel for the property and to help them get a sense of what they can do with it. For example, when you’re selling a home, you want to include plenty of photos with the listing and hold open houses so people can get a feel for the house. You want to clear out clutter and stage your home so buyers can visualize themselves living there, without being distracted by photos of your kids.
Moreover, even though you’ll not have a lump sum of money to place against another piece of land or some other big-ticket item such as a vehicle or home construction, you will have the guaranteed income to match your payments, or some such new purchases, including the interest.   You’ll also get to keep a lot more of the money you’ll receive, because you’ll only pay income taxes in small installments over the years, rather than all at once, which is likely to bump you into a higher tax bracket.
A somewhat surprising fact about selling real estate is that it can be far more difficult to find a buyer for a piece of vacant land than it is for most types of existing homes. The reasons for this are many, but often they are related to either the location of the land or the amount of work or expense that might be necessary to improve vacant land for a specific usage.
I’ve heard that it’s very hard to sell land/property with a quitclaim deed, and buyers (whether investors or the open market in general) will only want warranty deeds. So without me having to spend $2000 or so doing a quiet title or using Tax Title Services to make the deed fully clean and marketable and insurable, could you go into some depth explaining how to quickly flip/wholesale land parcels that I’m offering and advertising with a quitclaim deed I got from the county? What do I need to know for this, and how do I structure it to make it attractive, and what steps are involved? Is this something that investors/rehabbers are fine with accepting (if the price is attractive?)
Have a pre-prepared contract and Form 1 statement at the ready, to be signed when you find yourself a buyer who is prepared to pay you the right price.  You must remember that on most occasions purchasers have a right to “cool off” on a contract that they have just signed which they can exercise at any time and for any reason within 2 clear business days of signing the contract.  It is therefore critical that you strike while the iron is hot.
If you have plenty of time and are not in a hurry to sell the property, and would like to do very little work I would suggest listing it with a broker. They will be able to create a listing for the property, answer phone call and emails, and handle the closing. The downside of this approach is comes at a price and you typically only get local exposure and most real estate agents who deal with both land and homes will most likely put more effort into selling their homes as the commissions are greater.
