Investing in small Multifamily - Philadelphia

Looking to invest in a small multifamily property (5-6 units) in Philadelphia around the fringes of University of City. It seems like the area trades around 7% cap rate - a bit lower in University City itself. Is it unrealistic to target IRR of 15%+ with a management company? I'm new to investing in real estate, so doing a good amount of research.  Will banks be expecting 80% LTV / 1.20x or 75% LTV / 1.25x? Is 30Y amort the max banks will go or will they accept 35Y / 40Y? With 800+ credit score.

Any other advice would be greatly appreciated. Any market intel for Philly would be great. Rents look a bit soft recently, but I'm bullish on University City and the areas around it. Looking for a 5-10Y hold. Looking for a newer construction with tax abatement and less maintenance.
