Specifically for multifamily properties.

I've looked on your website and found a great deal of useful materials.

My advice is to check out flip with Rick on YouTube or website.

If looking for stability, I would look at buildings built in the 1980s or newer, ideally townhome style instead of apartment style if a 4-plex, minimum 2 bedroom units.LEARNING RESOURCESI am going to try to keep up my blog here on Bigger Pockets specifically with 2-4 family units in mind.

I know there are specific instances where some leeway is ok, but in hindsight this was not one of them.2.)

There is a clear, easy to read book, probably available at your local library or bookstore, by that name, and a website and an active forum, (of the same name) to ask questions and get responses.

Keep in mind that when you are renting your place, these websites don't always talk to each other so check to see if your property shows up in a particular website. 

what state is the property in and what is it.. is it 1 to 4 units.. the website shows no licenes so there are 12 or so states that licenses are required for 1 to 4 unit no matter owner occ or not.

More specific: how do you personally keep records? 

Specifically, I am focused on wholesaling as a way to build enough capital to start investing in SFR/multifamily with a buy and hold strategy.
