Mortgage rates for investment home

[Rudy Manna]

I am from Seattle and reached a local lenders to finance an investment home in south-side of Seattle (Tacoma area). I got an financing from the same lender for my residential home purchase. Now he is quoting me 4.25% with 25% down. Is that competitive for Investment homes? The rates for regular home purchase is going at ~3.5%, so I was wondering if ~0.75% spread is expected for investment home.
