alot of this I think would be determined on personal goals of yourself and family followed by goals of your future for example I bought my first house 2 years ago small little 3 bed 1 bath thought great started now i have 1 5 year old terror I already see the drama of a girl in teens sharing a bath room -_- I would give ANYTHING to go back 2 years and buy a duplex "but I cant" sooo I now have great sweat equity built into my home and will be taking a heloc out on it to do my first deal. I am a addict when it comes to deals and look several times a day in my local market and missed some great deals how ever in my market I would suggest a duplex because in my city everyone works at the heart of it and the land here is just used up so its prime rentals either way I go home value has shot up as there is just no more land to build on unless you go out of town so SFH are overly priced so its a ruff cash flow, for me I will be doing a duplex for following reasons 1 more doors = more safety if a moves out b is still helping to cover my payment 2 its still 1 roof 3 I control the value of said property if I really make it diamonds = raising the rent to the cap it controls the value of said property. I am assuming you want to get a FHA loan which if that is the case MFH would be great as you come in gives you 2 years to rehab both sides or at least yours depending on if tenant moves out refi and move out to your next property and keep the ball rolling the roller coaster is always going to be the first property the first should help pay for the second second to pay for third and so on so forth hope this helps
