@Xavier Williams This depends on your level of experience and knowledge, the amount of time you have to devote, your tolerance for risk and your ability to manage a project with a lot of moving parts.

Since you're new to investing, go slow.1) identify how much time you can devote to investing2) based on nu. 1, determine whether you want to be active investor or passive one3) based on the conclusion in nu. 2, look into options available for either passive or active investors.I have a library of books.

I have devoted ALL my free time away from my full time career in Land Surveying towards learning and studying REI.

However, I just didn't have the time I wanted to devote to my career as an independent agent, a landlord, a therapist (my other profession), my family and achieve all of my other goals.

If you need to buy a vehicle in your company's name, that's a lot different then if you are just looking to segregate personal and business funds.If you just need to segregate your funds, you can just take out a personal credit card that you devote to purely business expenses and use it as a business line of credit.

So don't even bother with them.A good one has clients.. many clients.How many hours a week will such a marketing company devote to each client?

Since you don't have tons of clients, you can devote more time to the clients you have.

Currently I work a full time job in large project construction management and I want to devote time on the side to REI. 

As far as I know (and I could be wrong) there isn’t a specific sub group devoted to strictly notes.

In terms of being active versus passive, it is really up to you to decide how much time you can devote to real estate investing.
