However, keep in mind that the reason investors own rental properties is that with today's low interest rates, the payment and carrying costs for the investor are less than what they charge you in rent so they make a positive cash flow in addition to getting the tax write off's instead of you.
Did you know there are programs that will let you move in for $500 to buy a home if your credit is decent (doesn't have to be perfect) and you meet their guidelines?
Most first time home buyers I work with are shocked to learn there are still 100% financing options out there are grants and special programs to help pay for down payment and closing costs. For example, I am having a home built for a family for $191,000 that is using a program with $0 down payment and I have having the builder pay all but $1,000 of their closing costs!
Best of luck!
