You obviously don't need to pay 6% to a realtor, but you REALLY need to pay for a lawyer, title insurance etc. If it has been in the family for a while, I'd recommend a survey too.

You need an RE lawyer in the worst way because of unanticipated problems down the road (should they arise), and/or things like capital gains taxes, or other things that you may not know about.

Agree that you should speak to a lawyer. In my state the sale must be reported, and there are property transfer taxes paid by the seller based on the sales price.

Buyer needs at least a title policy & a survey, &, here anyway, the sale should be recorded with the county clerk to protect the buyer from, among other things, the seller's creditors.

If no sale has been recorded, & the seller has a tax lien, the house could be sold by the IRS, & the buyer wouldn't know until somebody came by with an eviction notice.

or the seller could die, & the executor could do a search of county tax records & find the house & list it in the assets of the estate & sell it.

or the seller could die, & leave "all my worldly goods" to his/her only child, & the child could take out a home improvement loan on the house & never pay a dime, & the house would be foreclosed.

or the seller could receive all the property tax notices & ignore them, & the county tax office could sell the house...

Really, you need a lawyer or a title company.
