@Blaine Gobler Welcome to BP! Your story sounds pretty similar to mine, I bought my personal residence 3 years ago and rented it to my brothers and a few other people while living there. It's such a great way to dip your toes into investing and I've encouraged countless people to get started that way.
I'm not a lender so I'll avoid weighing in on your first question. I can however point you in the direction of a few great lenders if you're trying to figure out where to start.
The market is definitely crazy but it's showing signs of returning to a bit more of an equilibrium. You can't really evaluate a rental in the future without making predictions about what rents/expenses/interest rates etc will be then. Rents might be higher 3 years from now but your taxes could go up 10% too or your vacancy rates could go up or any number of other things that are impossible to foresee. Rather than trying to predict what might be a good investment in 3 years and risking buy a bad deal now, I would focus on figuring out what makes a good deal now. As someone who underwrites dozens of properties a week, I can tell you that there are still good deals to be found.
Since you're making this your personal residence for a few years, start with what is important to you and your brothers. What part of the city would you be ok living in? Do you each want your own room and bathroom? Do you want a big backyard? Do you want it to be turnkey or are you ok with doing some repairs? Once you answer these kinds of questions, you can then start to figure out whether or not you can also make it a good investment. If not, then you need to go back to the drawing board on your strategy because it may be incompatible with your preferences. Does that make sense?
I'm always down to grab coffee if you want to chat more!
