There's no straight answer; it depends on your long-term goals. Since you are young, cash flow may not be as important as building equity by holding the property a long time. Less monthly cash flow (unless you need it to pay for college/live on/etc). As for me, my husband/business partner and I are looking towards retirement age and want cash flow as passive income. We don't care as much about equity (of course, we don't want the property value to drop).
You will have to do some research in the geographic area where you want to buy to see if there is a market/need for single family home rentals or if you can do well by purchasing a home and renting out individual rooms. The latter works well if you buy a house near a college or university and rent each room out to students. We are in the process of doing that here, and we are designing the lease so the rent is X per month no matter how many people are living there. In other words, if three people live in the house and one moves out, the remaining two people are still responsible for covering the rent. College rentals, at least here in the States, do very well.
I recommend you reach out to other investors who are doing what you want to do, and shadow them. Offer them something of value (i.e., make phone calls for them, find properties, etc.) and they will be more likely to give you something in return (i.e., advice, share connections, etc). This is ALL in the BRRRR book. I've found that the best way to learn how to do something is to work with/for someone who is already doing it, learn everything I can, and then go out and do it on my own.
Remember: real estate investing is NOT a get rich quick business. There is a learning curve. It takes time, practice, making mistakes (I can share a nightmare wholesale story with you), asking questions, asking more questions, and then asking more questions. Find a local REI group in your area and go to those meet-ups. Build your network of partners such as real estate agents, property managers, contractors, lenders, other investors, etc. Read the books you can find here on Bigger Pockets. If you are not a Pro member, it's DEFINITELY worth the $390/year to become one. This site is nothing short of amazing with what they offer (I'm sincere about this, no one paid me to say it). In fact, if you upgrade to Pro before tomorrow, June 28th, you get a 20% discount PLUS access to their new Insight feature, which will help you greatly if you are doing buy & holds/renting.
