Question for multi family investors about buying overpriced

[Renato T reyes]

I am currently looking  at a 4 plex the units are all 3br1ba units. They all rent out for 1500 a month 3/4 are rented out. This is also near a university and has been remodeled with a new roof. The current listing is for 400,000. I did my due diligence and the rental rates check out. My issue is when I look for comparables and tax information this listing is surely overpriced. 

My question is will I have trouble getting financing if this property is overpriced?  Do I overlook the property being overpriced if it cash flows that well?

If your rent roll is 6k on a 400k purchase price, you are in good shape. It will be a residential appraisal and sometimes if there are not a lot of 4-family comps, it's hard to gauge, but I find it hard to believe that four 3/1 units renting that well, even with one vacant, won't appraise with comps at 400k. What city is this in?
