I'm going to take a completely opposite stand-point from everyone else.
You absolutely need a website for lead generation to start.
First, it costs $50/mo. That is NOTHING. If you can't chalk up $50/mo, don't even bother stepping up to the place of wholesaling or marketing. If you're thought process is ("Let me save $50/mo so I can build a custom site!") then you immediately need to change that mind set and figure out where to get $50.
Second, SEO takes time. You can' just TURN IT ON and think leads will roll in. Depending on your market, it can take, 3, 6, 9, 12-months for a page SEO heat. Then, there's all the little things you need to do to grow your traffic. Backlinks, social media, social shares, regular and fresh posts.
Third, even if you'r tech savy - do you really want to be running a website on your own? That's a giant pain in the butt. And if something bugs out, breaks, has to change - you're going to have to be paying someone or doing it on your own.
Fourth, as to the benefits of Wordpress, InvestorCarrot is a word press based site? Not sure if there's a big difference.
The one thing I do agree about - is you will need to take time to customize your website. Remove the text everyone uses and re-build it.
However, that is absolutely not because I care that my site looks the same.
People go into the site, enter info, click get offer. Sure, they might surf some more. I highly doubt sellers are looking at a site and thinking (let me think about clicking the form and go to other sites, see if they are similar, and comp back!).
I use IC, my conversion rates are always super high. Bigger challenges are generating cost effective traffic.
