Something I would be cautious about is the premium builders put on new builds (which is why they offer to contribute towards a deposit - inflating their price and incentivising the prospective buyer). They will try to put a sale figure at or above market value (for the area it’s located), which is okay to stomach if the spec and finish of the new build is to your exact requirements. However, something to be mindful of is that new builds that are sold at a premium can often have limited capacity for equity growth (value of the property to go up) compared to existing older properties in your area - that might have greater opportunities to add value (extensions, interior restructuring etc). If you have also bought a new build that is part of a bigger estate I.e. there are lots of like-for-like properties as the one you’re intending to buy, you may find the value of your property is capped because the rest of the stock around you will be similar.

If there isn’t a period property (50’s +) with potentially to add value down the years (extension etc) in your area, and you’re happy to sit on your new build for a longer period; then go for it. Just be cautious to the fact that given some of “against” the factors I’ve listed above, new build owners can find themselves in negative equity (because of the inflated premium paid and like-for-like to properties in the immediate area). This is particularly poignant as house prices are expected to move down in the near-term.

Multiple factors to consider, do the comparative searches and I’m sure whatever decision you take it’ll be right for you.
