While its important not to go over the top, a well-presented dining room will always have an injection of colour. It doesnt have to be bright yellow. It could be a subtle light green with matching curtains that have a pop of pink in them.
If you have an outdated dining table and chairs, it may be worth investing in some new furniture to help present the room in the best way.
It is likely that you will take the new items with you and so it wont be a wasted spend and could end up selling your home if it helps to make the room appeal to buyers. If you dont take them with you and the buyers like the space, you could offer to sell them - this is particularly handy for first-time buyers.
If you buy a six-seater, eight can usually be accommodated at a pinch — the larger the diameter, the more people can be seated. On the other hand, rectangular tables have limited seating spots due to the position of the table legs and because only one person can be seated at each end.
