Generally exactly the same way as is done when dealing with a real estate professional. Make sure that contingencies are included in the contract. The usual contingencies are as follows.
• The home is appraised for an amount consistent with the sales price.
• The buyer can obtain a mortgage.
• The home passes a professional home inspection.
• The home passes a pest inspection.
• The seller can provide a clear title, free of any liens.
Make sure that things to be left with the home are itemized within the sales contract. Make sure that the contract states which party will pay for fees and other costs such as transfer taxes, escrow, title fees, survey, cost of inspections, and other costs. Finally, make sure that the date of possession and closing is negotiated and clearly stated on the contract.
