Good morning @Ismael Mathurin,
What you are doing seems like a good plan. Wholesaling is a job. It can have a good income but it can fluctuate from month to month. Getting into small multi family would be a way to start getting a consistent flow of money. This way, pursuing wholesaling would be safer since you could survive a slow spell. My goal with small multi family was similar. I wanted to house hack and stop paying for housing for myself. Then to use the passive cash flow to increase my savings rate.
What you may want to consider when looking at multifamily:
First, you may already know but there is a difference between 1-4 units and 5+ units. with 1-4 units lenders look at them as residential. Once you hit 5 or more the loans become commercial.
When looking at multifamily the number of units can matter. Here has been my experience and what I have seen three people do that I have helped. I am going for duplexes. The first one almost eliminated my monthly housing costs. If I had gone for a 4 plex I may have completely eliminated it. It can be hard with a duplex to eliminate your rent and add cash flow.
I would do your own research on the rents in the area you purchase in. Sellers can list the rents and put in a clause of "buyer to verify" I have seen rents listed that were too high for the area and in one case the tenants had a lease that was too high. They had not paid a deposit and the owner had worked an extra $200 a month into the rent for the year. This made the place look great if you just saw the monthly rent. Make sure that the deal is good if you had to rent out units for 5% less than the average in the area. Trulia, Craigslist etc. are what I have used to see what the rents are.
I had a lot of apprehension in my first deal. I recommend going to any local meetups. Even if people are doing things a bit different than you plan to you will learn a ton.
Good luck.
