Question about buying or selling a house or property...

[KarTek]

Just out of curiosity, could I walk up to someone with a suitcase full of cash and use it to buy their house?

Vice versa, could someone give me cash for my house?

What are the legal obligations of a house sale?

All sales I'm familiar with have been through a realtor, paid through a loan. I've never heard of just plunking down cash for a house though, in this market, I can see it happening with the bargain prices you can find in some areas.

Thanks!
