The hard part, however, is getting your neighbours on board if that’s what you’d like to do. Offering a developer a larger parcel of land can be more profitable for them, and therefore more lucrative for you. This will require negotiations and time, possibly between yourself and your neighbours or between your agent and the neighbours. Be prepared that not everyone else will want to sell, even if there’s a big payout promised. Make sure that the extra effort will be worth the final sales result by comparing an estimated selling price for your home with what your portion of the sale will be if you sell to a developer.
If the property is part of a Home Owner's Association (HOA) it will most likely have even more stringent restrictions in place to help maintain the “quality” and formality of their neighborhood. The idea is to keep any bizarre behavior OUT of the neighborhood (e.g. – cars in the front yard, lawns nobody takes care of, houses that look out-of-place or aren't built to code). 
The way that we found it was by checking our local county tax assessor site and seeing that it was vacant and owned by a gentleman who lives out of state. It wasn’t on the market, but I asked our realtor to contact him and low and behold he is willing to sell (it was inherited). As soon as we were ready to make an offer, he stated that he wants to go forward with an independent appraisal to see what the value is since he does not live in the area, which I understand (he is also a realtor in CA).
Land Requires Different Sales Techniques – A home has a kitchen, bathrooms and a façade that can be visual and photogenic. You can hold an Open House for a home and walk a buyer through each room to help make the sale. Buyers can easily visualize themselves in – and fall in love with – the built home. It’s just not the same for vacant residential lots and land.
