The concept is good, not so sure the deal is.
What can you rent the house out for once you decide to move out? Will help to determine if it's a good investmentIf
A rental that doesn't cash flow is not a good investment unless you have a high level of certainty it will appreciate in value.
If it cash flows after you move out, and you can get in for 2,000 and live there for free for a few years, if that's a lifestyle you want , may be a good deal.
I helped my nephew get into a two unit, with an FHA loan, similar situation. One unit almost covers his payments and the other hecrents out two bedrooms to friends and more then covers his payments, so he lives there in essence for free. Got him out of his parents place, no rent and allows him to save money for a few years. And the property will have a nice cash flow when he moves out and rents both units.
Run the numbers, think it through, make a gooddecision, you will do well.
