Hi Noam – I don’t check them all, every time. Many of the issues can be immediately ignored based on where the property is located, it’s size, and what it would most likely be used for, etc. For example – if a property is in a mountainous region, flooding will almost never be an issue. If the property isn’t ideally suited for building, then utilities and septic don’t matter. You get the idea.
Do you know if the developer had a local brokerage do the sales for the project you mention? You might want to contact the developer, but I'd also suggest you speak with a Realtor first to get a market analysis for the value of your property. Then decide if you want to put your property on the market or if you want to explore contacting either the developer or the owners of properties adjoining yours to see if there is interest.
As for whether the seller will accept a lower offer – you’ll never know until you make the offer and wait for his response. It could obviously go either way, but my philosophy is usually to err on the lower side – because unless he’s got other buyers waiting in line (which I doubt he does), you can always come back with a higher offer later if you really want it that badly.
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.
