SC, no problemo.
Martin - suggest you have a read of the following thread that is relevant I believe to your point. In doing so I am assuming you are taking a situation where your "real estate agent" is a PPL possibly looking to share costs.

There are a number of issues that have wider legal implications for the scenario you described. In particular the ANO uses a term called "valuable consideration". The legal beagles state that this has a much wider interpretation than what I would have at first thought eg: cash. Another factor to consider could be the possible invalidation of the aircraft insurance (presumably hull and public liabilitity) if a flight can be proved not to be for pleasure/leisure purposes.
