Be Careful
This "database" is a good idea, in theory.
I have a couple of thoughts to contribute.
You should be very clear on the purpose it is to serve. For it to be worthwhile information, the audience served by it should b clearly defined.
For example, is it an owners guide to help them determine a fair market value of their shares? Or, is it a buyers guide to help them determine what price they should pay?
It is easy to say that the data is what it is. It serves both equally. But common sense would refute it. The fact of the matter is that the contributor population is limited to those who participate here on TUG.
If you are a seller, your buyer is likely not a member of this board.
That buyer is not influenced by the data.
But, if you are a buyer, the information is relevant.
Assuming both buyer and seller have access to the same information, the buyer and seller are almost assuredly not transacting with each other.
In fact, those owners here who are considering the sale of their share probably will outright resent a buyer who gloats over the "steal" of a deal they just made. Marketplace psychology naturally leans toward establishing market price by the lowest price paid. No one wants to pay more than someone else did.
Bragging rights rule. From this very mindset "fish stories" are born.
The integrity of the information is further compromised by the only trait that can be trusted; self-interest.
I am not simply being skeptical. It is the way of things.
Look, lets be honest. One does not need special powers of observation to recognize that on this very board helpful and sincere intentions co-exist with one's self interest without apparent contradiction. Information is shared until it is counter to one's self-interest.
Since almost all are Starwood owners, views change when owners and buyers become sellers.
With this fact of life as a backdrop, a seemingly good idea can become a bad one. Be careful what you ask for.
Having said all of this, you may want to consider adding the following information to the profile:
Use year data. - Who received it, and who paid the annual fees associated with the use? It is worth a couple of thousand dollars in the transaction.
Closing costs. - How much and who paid it. Buyer, seller, or shared?
Who is reporting: buyer or seller? If buyer, only the above is applicable to the price paid.
If seller, the net proceeds are relevant. What were sale costs? These influence the accepted sale price. If not relevant to the data base objective, simply acknowledge it is a buyers data base.
DavidnRobin bottom-lined it: "my point is - that it can go both ways - and unless everyone participated fully (and honestly) - the data will be skewed - and only really gives advantage to the buyer. "
Again, every owner is likely to be a seller at some time.
Disclosure: I am a broker. Before discounting my remarks, consider this: I am the only one to whom the outcome is irrelevant. I earn commission on the sale, irrespective of price.
I do, however, strongly believe that softening markets help no one in the long run. Not buyers, not sellers, and certainly not overall activity (from which I do benefit).
