If it is your main keywords, you could well pay anything lest someone else picks it up. But then again if it is 3 words, it is easy to rank even with a page... if you have a good brandable main site with a single word. But 300 i not big money because if it is ur main target, then I am sure the search volume must be big enough to get u 300 in a month.
Sometimes spending $1000 today on something is cheaper than spending $500 on the same thing a month later. You could turn a $10 investment into $100 within few days. In other words only you know the answer to your question. And the only way to get us to help you find an answer is to give us more info. It's like asking someone that don't know you if your wife loves you
You are not revealing the domain name.... with knowing the exact domain name its quite difficult for any one to suggest you any thing. However, if you have decided to buy the domain then go one and purchase as its you who will pay the money and would get the advantage and disadvantage related to that domain. Good Luck Thanks & Regards Priya
Ok.. So here is some data to help you out. Some similar past 6 months sales of 14 letters 3 words .net domains FastWeightLoss net $4,500 WeightLossDiet net $1,888 DesignYourLife net $1,888 FiveStarHotels net $1,420 MyFamilyHealth net $1,305 LoveYouForever net $1,088 HouseOfHotties net $905 WebDesignGroup net $599 RyanBrownMusic net $210 CompModCentral net $89 FreeOnlinePorn net $70 The range is huge $70- $4500. So again it ends ups at what are the keywords. You cant genaralize the value of domain. See if keywords go well with each other. As far as online appraisal tool are considered I would say don't look at the value, however focus on additional statistics( I am assuming you used Estibot). Hope This helps
Congratulations! if you have got domain control panel, may we know your new domain name- if you don't have any problem?
