Top 10? How about just 1? But if you want 10, I will give you 10. Ready?
10. Did I mention, Price?
In all seriousness, though, if you reserve price for your own house is higher than any other buyer's out there, then you WON"T sell your house.
There are other considerations too, and the most important one is marketing. How is marketing related to price?
A. If you get reach 10% of the potential buyers, you will have to sell for lower price,
B. A house might sell for $100K to a non-investor, and $90K to an investor (because to an investor, it is worth less due to cash flow reasons). So if you market to investors, you won't get the price you want,
C. If you have marketing issues, e.g., carpet has stains and you are primarily marketing to first time home buyers. First time home buyers will be arguing about every little unimportant details.
D. Your house is only $100K, but you are marketing to people who want to spend $200K. Paradoxically, while the potential pool of buyers can easily afford your house, they don't want it.
There are many ways why you can lose potential buyers:
(I) Your agent is not responsive to inquiries,
(II) You have too many requirements (I can not show today, tomorrow, or any time this week),
(iii) Your house does not show well. E.g., you come in, and the place smells of urine,
In short, price and marketing.
