re: Buying house from for Sale by owner

If you've bought three houses (all in the same state), then you should be familiar enough with the standards and practices. At least in my state, if you're the one writing the contract, more of the burden is on you, should something not be clearly spelled out or there's some sort of misunderstanding. If the seller makes a counter and inserts some conditions or language that you're not sure about, a good real estate attorney can help.

If it's a pretty straightforward/bread & butter transaction, do the contract right and you should be fine.
