I've seen some people comment about losing the link value of domains that have expired and picked up, but what about non-expired domains?  Let's say a competitor is going out of business and they still have a year or two left, and we buy their domain and site.  Is there a risk changing registrant info and registrars, even if I keep their site up and mostly the same as before?  I was under the impression that I'd want to keep it under their name so as not to hit the uber-reset button on the domain's inbound link value.

Here's a test I have in process.  I bought an old $5 closeout domain from Godaddy TDname expired auction.  I put a quick minisite up and linked to it with a crazy anchor text phrase.  The domain is ranking for that crazy term now.  It's gone through one pagerank update and I'm waiting for a second to come.  Then I'll redirect the domain to another minisite.  I suspect the second site won't rank for the anhor text, but we'll see.  
To sell a domain name, one should learn to price it. Many sellers fail to sell names in the marketplace, simply because they overpriced the domain, and thereby lost the chance to sell it. A lack of knowledge leads to erratic pricing. Experienced buyers will not try to bargain, unless you have a very rare name. A seller should therefore, understand how good the domain name is. What price will he get from a buyer? What suffix does it carry? For instance, .com names are likely to sell fast and will bring greater profits than, say .info names. Similarly, .net, .org and .in domain names are the best to make decent profit.
Adding domains to our Premium Listings on our website before you sell will give them more exposure to the community. We’ll offer an appraisal for your domain to give you an estimated selling price, and you can adjust that price at any time. We also offer a comprehensive breakdown of our commission rates for all premium listings, so you can easily understand the process.
Really depends on whether you want it to be passively marketed or actively pitched to investors and buyers, as well as how fast you want it sold. It also depends on what you're selling. What you're selling is only worth ANYTHING if there is an interested buyer. And it's only worth what the buyer is willing to pay for it at the time you want to sell it, not what you currently owe on your RV. This is a common misperception among folks trying to value domains before sale - they pick some nebulous method of pricing it that is not based on the market or history or sector demand, but rather on what a vacation costs or how much they owe on their boat. Good luck with that. So it really depends. If you have something that you feel has demand, you'll potentially get a higher price for it by NOT needing to short sell it quickly for cash and being able to wait while a broker packages and pitches it. 60-90 days. That will always get a higher price than just listing it in a database and hoping someone will see it and be interested. The problem is, good brokers are few and you're going to need to see if they will represent you in the sale. If they don't believe they can sell it at all, or they don't believe they can sell it for what you owe on your boat, they'll decline your offer to do business with you because you're being unrealistic.
Use escrow services for direct sales. When you are dealing directly with the buyer, make sure that any money that is transferred goes through an escrow service. This will ensure that all checks clear and that you aren't left with a bounced check and no domain. Escrow services may add a few days to a sale and cost you a percentage, but they can save you a lot of heartache.

It is mind boggling how local search engine optimization has grown from a tiny market to a mammoth industry within a span of ten years or so. This is also one of the reasons why focusing majorly on local names is profitable. From doctors to pizza parlors to salons, everyone wants to see their business thrive on the first page of Google Search results with the help of target keywords.

The domain name industry is quite similar to the real estate industry in a lot of aspects. There are end users, brokers, consultants and domain flippers or “domainers”. Domain flipping works similarly to buying a house, renovating it (or even sometimes just sitting on it) and then selling it again at a higher price point. The gist of it is: you’re purchasing a domain name and betting it’s worth (or will be worth) more than you paid for it. If you’re right, you get a nice paycheck and move on. Those who make a living out of this just rinse, repeat, and scale.
