3.Would I be better off incorporating and putting homes in the business name or will that make it harder to borrow against it?

Let's see how that goes :)I'd definitely say try to incorporate the kids in the biz if they're old enough.

Now since I have a logo now and a printer I'll start a serious mail campaign of expired listings near the markets of colleges.

Company logos cannot be used for that purpose.

A few months ago, I heard of a politician talking about doing away with private ownership, won't mention the political party but that's obvious I'd think, saying property should be in corporate hands.

As Steve mentioned, you'll need to take Articles of Incorporation, company authorization for you to act (depends on the entity) and your ID to make a demand, or deposit twice in your account and let the bank clear it.

The sign in the yard with your name (maybe that small emblem as a logo) relates your name to these elements and to the quality of your work.Put the sign up as soon as possible and get started, it indicates how long you'll take on the job.

Or can it be something catchy like the rest of the hot start ups in silicon valley that rely on logos and branding?

There are many benefits to this but it has to be incorporated at the right time.

BTW, here's some other things that you do not need in order to wholesale. a website a company name a logo a "team" a Realtora business plana mission statement branding etc
