What sort of people would respond to an ad like this? Some will be tire-kickers and the curious, but a good number of callers will be investors and real estate agents. I had the number in the paper forwarded to a voicemail service, and it's a good thing I did as there were a lot of calls! I find that those who are just curious about the ad tend to hang up without leaving a message, so that takes care of those that aren't serious.
Step 3 is to learn about supply, especially in the preconstruction marketplace. In some areas, there are very few projects on the books and in others, there are 15,000+ units expected to emerge within 1 zipcode, in 1 year. Same is true for investing in houses. In you are competing with a bunch of new houses that are coming on-line, then rapid price escalation may be limited. For most savvy investors, they like to see lots of demand with very little supply which is nothing more than common sense.
If you believe markets are generally efficient and prefer to invest in an index mutual fund to achieve an index-like return, shopping for the best index mutual fund based on low fees and a low expense ratio makes good sense. The portfolio manager of an index mutual fund endeavors to invest the fund's assets to track the index as closely and cost-effectively as possible. Larger index funds have an advantage in that they can spread their operating costs over a larger asset base.
