Today, I went to the house seller place (sorry, don't know the name. Near SAPD base). I was viewing some house price, but I accident press the "buy this house" and I don't even like that house. So my suggestion is added the Yes, No after you press the "buy this house". It would be like this:
Do you want to buy this house?
Yes No
Also my other suggestion is added the sell house like when you sell a car, it would be useful if you accident buy a house that u don't want to and when other player that don't wanna buy that house.
