@ Steve A. - I'd suggest to look beyond the cap rate. Yes, a deal with less than 5% cap is most likely not going to work (because the cost of money is higher, and now interest rates are around 4.6%-4.9%). BUT if you buy a property with a low cap, then renovate the units/amenities/reduce expenses, raise rents and by that improve your NOI (net operating income), then the cap rate after 1 year will be significantly higher. If the property is distress, or if you were able to increase rents significantly ("forced appreciation") - your cap at the end of year 1 ca definitely be more than 7%.
Even a 7% is great, but depends on the market. If you buy at 7% or even 12% cap, but there is no appreciation, then your total returns will be much lower than a deal in a strong market/location with a 6% cap and if you were able to see it after 5-6 years at 5.5% cap.
Just wanted to share a different way of looking at cap rates...hope that help!
