I have several websites myself with good domain names... zero leads for me.  

I have a domain, but dont like the name (long story) defaultloansolutions.com I figured that my facebook url states my purpose more.

The domain is cheap, and you could sell the domain in the business to someone else that's properly set up or partner with that personThe bottom line here is you need branding that says where you're at and what you do

Also make sure you have a polished professional website and email with domain name.That being said if you want to send a letter make sure to use a real stamp, professional letter head and good quality paper.

Actually, I heard those ladies interviewed just today on the BP podcast, and when I looked for their website, it looked like their domain name was for sale, but I found another group of women investors.

Whois.sc is like a whitepages for domain owners.  

Be determined and bend over for NO ONE. know what you want and know your worth.2) Learn as much as possible about wholesaling, the laws and rules concerning this to stay in the legal zone.3) Get a killer domain name and learn how to leverage a website to generate deals.

Ahrefs and other sites that analyze SERPs show that unless the site has a great domain authority it takes almost a year for most sites to rank for even slightly competitive keywords on Google searches.I just know a ton of people who venture into SEO, it doesn't happen fast enough and they give up but that is with everything.

Or should I set up separate/additional domains names, i.e. webuyhouses . com etc?
