From SFH to 4plex - analysis

[Thomas Handy]

I'm making the leap from SFH to fourplexes. I've plan to look at a fourplex this weekend and make an offer and put down 20%. The property is listed for $109,000. Taxes are $849/yr and insurance will be $1766. The vacancy factor would be 5% and it's currently renting for $1900 a month. I'll use a property manager for 10%.

Based on my estimates the mortgage would be around $442 a month. Am I missing anything?
