@Nate Turnerwhat you'll want to do is work backwards from your goal. If you want $50k in passive income start with how much you can get per property you own in cash flow minus, repairs, vacancy, cap x and any mortgage payments. Say it's $400 a month you divide $50k by 12 months then divide that number by the $400 and that will give you your goal of how many properties. That 10.41 for those who don't want to do the math.
Provo/ Orem has great opportunities you'll want to make sure your buying right in those areas. A lot of the homes with basement apartments are not legal and you will not be able to move on and rent both unites like a duplex. Provo/ Orem are very picky about this and you will get into trouble if you don't follow the rules. Just an FYI.
Orem has a lot of 1970's homes that are in the life cycle for a new remodel which could add a lot to your equity so that might be a good route depending on your skill set and what loans you plan on doing.
