I agree with Anson that a multi-unit would be great, and occasionally I see one that works for an owner occupier, but you could probably do just as well with a couple condos.  

If you're starting out and need a lower price point to get into a property, if you're not interested in maintaining mechanical or roofs, if you want managed costs (HOA's) versus the occasional big ticket cost (hot water heater fails), they can be a great option.  

My wife and I are very excited about this opportunity and we have decided that we want to focus on 2-4 unit multi-family investments with the occasional SFH for buy and hold purposes.

Sure I have strong opinions, and occasionally I am forcefully and publicly WRONG.

For me, the benefits that make it worth it are...1) Credibility with sellers, buyers etc.2) MLS access3) The option to list the occasional property if I want and earn extra cash through a comission4) Not having to rely on a realtor for  realtor related tasks like gaining access to properties for sale.

I fix and flip and occasionally hold and rent.

As I understand, all rents are considered to be part of your income, in a way or two, so if you live rent free with an occasional handyman work, i think that will work out best for you, being 23 & 21.  

Even though we has a good amount of savings, I was loathe to touch it because I didn't have a consistent way of making it grow (banks pay less than 1% and stocks are too volatile to count on stable growth).Now, with over a dozen buy and holds that cash flow well and some other passive income sources (dividends and notes), I feel less qualms about splurging occasionally because I know the passive income more than pays for it.

I think I would forward a video to PM occasionally so that when I ask about my property they better assume I have others eyes on the case and I already know the answer to my question

I performed ALL other work by myself with occasional help from Family members: Complete Electrical Revamp (New wires, Panel, Meter Base, outlets, etc), New Pex plumbing, Shed revamp, Landscaping, Windows, flooring..and basically everything else.
