Are the smaller developments a bit rarer to come by?
Yes, but not unheard of. Ours just showed up when we searched for new builds on Rightmove. You might not be able to tell from the listing but we could see that the house looked really good, and then when I went to look I saw that there were only 3 other houses built next to it. I asked the estate agent about the developer and they said they were just a small local developer.
Good to know it wasn't an issue to sell on afterwards - Did it increase in value even though it was leasehold?
Yes it did. As with all houses it just depends on the house; all houses can lose/gain value. We had a city centre townhouse in a desirable location so obviously it gained in value.
The house we have now as well will certainly gain in value over time because it's a desirable area with good schools.
I'd look at the overal square footage - our line in the sand was that we didn't want anything less than 1500 sqf. The house we bought is 1600 and has a utility room, and 4 beds. Not massive bedrooms but big enough, no box rooms. On paper we might have liked an even bigger house, but at the end of the day you have to compromise somewhere and this house is big enough for us, and it means that we are now really close to amenities, park, school, public transport.
I've been to look at many new build developments over the years and you do definitely see some where you look in a room and think - this couldn't even fit a wardrobe and a double bed! You also see some that just even in the show home look cheap and flimsy. Feel the doors, banisters, fittings and fixtures. Do they feel solid?
Ignore the promises about things that will be built nearby, like a poster above said, that never materialises...
With snagging, don't get too stressed about it. Just go round, look closely and see if there is anything that jumps out. Normal things are nail pops, uneven paint, scratches, little things like that. If there is anything serious that you find out afterwards they have to fix it anyway. If you are very worried about it you can get a professional snagger.
