This has been discussed before.
In a moment of madness, I made an offer on a house right in the braking zone for the 2nd chicane on the inside of the track. I suspect it's still on the market given how much they wanted for the entire lot (which was pretty big and included a pond and trucking depot). I offered them 100K euros on the house and pond but they wouldn't separate it from the depot and wanted 300K all in. Obviously not worth it for a place I'd use once a year living here in the US. It's not exactly in a desirable place the rest of the year so rental potential would be pretty dodgy based on the consultation I had with a local rental property expert. The ACO throw in Tribune seats for the race and not much else. Access was by mud road through the woods and in inclement weather would probably have required all-wheel drive. It just wasn't the right deal, even though the vantage point was spectacular. I couldn't get the idea of leaning on my garden gate behind the armco out of my mind.
I'm so glad I deep six'ed this idea and went with something here in the States that's more "usable" than a weekend a year.
If you've looked at any of the residences on the Mulasanne, many appeared to be falling to pieces (like many of the rural establishments in the area). The concept of getting to them during the race is not practical in my opinion. There is no road network in the woods - just mud paths. And unless you're a family member and have a car credential, the plod won't let you back there to the homes anyway.
