Hello.

My mother owns a low cost single storey terrace house (freehold) and we have the intention to sell it (when the time is right). The property is already paid off and the deed is already returned from bank.

I have tried looking around for the procedure to sell off houses, but apart from the advice of just consulting a property agent, I can't seem to find any other info.. I'm sure there's already a post regarding this, could somebody here point me to the right direction? A website detailing the steps perhaps?

Also.. I'm confused about this part.

Recently my friend's mom sold off their house, she said they sold it off for 1.1 million instead of 1.3 million because they wanted it in cash. I'm quite confused, if you were to sell off the house and the new owner approaches a bank to borrow loan, we will only receive the money in parts is it? not the full lump sum? 
Intention to sell: feel that property appreciation already stagnant, won't get that much higher than current value, so sell and use as d/p for next house (landed as well).
