Is it able to sell and buy a house at the same time? Yes, it’s doable. But you need to remember that it’s not a common idea because of how complicated it is. It can create a dreaded property chain which may lead to stress and chaos if you don’t know what to do.
If things seem to go South, you can always have the short-sell option. A short sale is a condition when you’re selling your house at a lower price. This basically means that you end up ‘short’ on paying your obligations in the form of mortgages.
The first house selling process, and the most usual one, is directly done by the owner. This means the owner will use a minimal to none of other parties involvement to sell their properties.
