Buying land to build a property can be a good investment. It could also be a good investment if you buy the land and it goes up in price, for you to then sell it on to a developer. Whether or not it is going to profitable for you depends on a few factors:

• How much does the land cost? If it is being sold for more than it is worth, then this isn’t really something you should be considering. You ultimately probably won’t get as much as you should out of the plot, as you will have overpaid in the first place.
• Planning permission. You need to know you can build what you want to on the land. It will often come with planning permission for certain types of properties, so make sure you check the deeds first.
• Location. If you buy land with the intention of building dwellings, will they sell?
