offer sent by email

[Ignacio Val]

Hello, I'm selling a house and accepted an offer that buyer sent me by email.

1- Is this a legal offer that obliges me to take the house off the market and can't accept more offers?

If not...

2- Tomorrow I have a meeting with buyer and will ask him for a formal contract and a deposit.

Once he sign, I understand that I have to take the house off the market and no more offers accepted, is this correct or the process continues open until the closing date?

I've read that you can still sell a house stating that is "under contract"

Thanks,

Ignacio
