Best financing option 5% conventional vs Rural Development

[Joe Fornasiero]

I have found a home that I am interested in purchasing. I'm planning on living there for about 5 years then converting it into a rental property. My I'm trying  to determine the best route in terms of financing. If I wanted to convert to a rental would I need to refinance the RD to a conventional and potentially get stuck with a higher interest rate? How does RD compare to a conventional in regards to long term total amortized costs?
