First, find experienced professional advisers. Arranging the deal yourself to avoid fees is almost certainly a false economy. An experienced agent, a solicitor and importantly, an accountant, are all essential before any sale negotiations are begun. Developers will have strict criteria for the land they wish to purchase in order to maximise their own profits, so obtaining the correct advice at the start will help ensure you can offer land for sale in the most appealing way to the developer and lucrative way for yourself.
Very good question, Trevor. We plan to do a blog article on this subject soon. You are pretty much on the mark with your example of 25% of the final to-be-built home’s value as a rough guide to a lot’s value. You’ll see that some markets use different valuations (even within the same city or region), but in many markets an estimation of the value of the lot generally can range from around 20% of the home value (for more rural or lower price point homes) up to around 30% or more (often for higher end communities or for urban/infill areas with less lot supply and higher home prices). Of course for some lots/properties these rules simply don’t apply, like oceanfront lots or land with other unique characteristics.
Comparables for land can be trickier than for home sales in your area. Although the assessor's valuation on your taxes can provide a starting point, consider factors like whether your property has utilities to the property line, views, zoning and any preapproved building plans to determine its worth. Location is always one of the most critical factors. In San Francisco's Pacific Heights area, for example, a buildable cul-de-sac lot of less than 4,000 square feet can sell for more than $9 million.
We found a really great 2 acre property zoned rural residential in the area of town that we really want to live in Oregon. It is the only lot left in the older established subdivision, so it has city water but would need a septic (which everyone in the neighborhood has of course). One big issue is that it is basically a forest. The whole lot is full of trees, huge and small.
We hope this helps provide valuable insight for landowners about the pros, cons and items to evaluate when considering subdividing your land. Check back soon for our second article in this series about Subdividing Land: Tips for Landowners from a Developer, where we will describe some real world issues that we have seen in subdivision attempts. Plus, the third article in the series will provide hands-on details about the steps to take if you decide to subdivide your land into lots.
Market for Land is Less Active – The market for existing homes is almost always more vibrant than the land market. There simply are fewer numbers of buyers for vacant land than consumers looking for homes. Start marketing a new home listing and a new lot listing when both are desirable and priced well, and you generally can expect fewer contacts about the new lot listing.
